In the Use of the Analytical Balance activity, you determined the volume of a drop of water by two different measurements methods. Three quantities were determined: mass of water; volume of water; and number of drops. Provide an explanation for the least accurate calculation among the three quantities.
Volume calculation will be the least accurate calculation among all three calculation because the number of drops of water can be easily counted precisely also the mass of the water can be calculated precisely but not as precise as the no of water drop calculation, But if we talk about the calculation of the volume of the water then there is a chance of sticking the water droplets to the wall of measuring flask which will give the error in the calculation of the volume of the water drops.

1a. The masses of five paper clips: 5.123g; 5.117g; 5.124g; 5.120g; and 5.126g. Suppose you were asked, “What is the mass of a paper clip?” What is an appropriate statistical response? Include information on variation. 1b. In the activity you determined the volume of a drop of water by two different measurements methods. Three quantities were determined: mass of water; volume of water; and number of drops. Rank the three quantities in order of least to greatest error in their...
Question 11 You use an analytical balance to measure the mass of a weigh boat and record a mass of 1.5624 g. You then add some NaHCO, to Not changed since the weigh boat and give the welgh boat to your lab partner to measure. Your lab partner mistakenly forgets to record all of the digits on the balance and records a mass of 1.92 g What is the minimum number of grams of acetic acid that you would need...
Could you please help me to solve these question with all
parts, including graph? thanks so much!!
We were unable to transcribe this imagenumber of drops volume of solution, mL concentration, drops mL-1 (Eq. 6) For example, if the solution you use to determine the spectrum of the food dye, which we shall call "Solution 1," was prepared by adding 1 drop of food dye to 40.0 mL of distilled water, the concentration of the solution is found using Equation...
I need just CONTROL VOLUME & ASSUMPTIONS
02. Water at 25 °C is circulated from a large tank, through a filter, and back to the tank as shown in the figure below. The power added to the water by the pump is 271 W Determine the flow rate through the filter. In your solution, follow these steps: Summarize the problem by stating what is given and what needs to be determined State all your assumptions Show the control volume chosen...
Part A Part complete Using your graduated cylinder, you calibrate the pipet you will be using and the values you collect are as follow. What is the average number of drops per mL of benzene. 21 drops 22 drops 17 drops 20.0 drops Part B Part complete After calibration, you use the oleic acid/benzene solution to form a monolayer. It takes 8 drops , 9 drops and 6 drops before the layer on the water solution starts to make a bubble tha...

Two methods were descibed for determining the volume of the
flask used for the molar mass determination. Which method will give
a more precise determination of the volume? Why?
When two acceptable determinations of the weight of vapor needed to fill the flask have been obtained, remove the foil cover from the flask (do not discard) and clean out the flask. Fill the flask to the very rim with tap water, cover with the foil cover, and weigh the flask,...

7-3: Analysis of a Ferrous Chloride Sample Titrations provide a method of quantitatively measuring the concentration of an unknown solution. This is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) In oxidation-reduction (redox) titrations, the voltage resulting from the mixture of an oxidant and reductant can be measured as the titration proceeds....
Slot machines are now video games, with outcomes determined by random number generators. In the old days, slot machines were like this: you pull the lever to spin three wheels; each wheel has 20 symbols, all equally likely to show when the wheel stops spinning; the three wheels are independent of each other. Suppose that the middle wheel has 6 cherries among its 20 symbols, and the left and right wheels have one cherry each. There are three ways that...
