A student is required to deliver 4.35 mL of a liquid. Comment on the appropriateness of using the following to complete the task.
- 10 mL graduated cylinder
- 50 mL graduated cylinder
- 10 mL pipet
- Buret
The student use buret to deliverd the liquid. Because in buret get exact quantity liquid. In buret per drop is count. If we first calculate 1ml liquid equivalent to how many drop then we easily mesured the liquid.Or the student first assigned the 0ml to 4.35 ml and started to delivered the liquid from 0 ml and stopped the buret when the liquid reach the point 4.35 ml.

There will be a short quiz held at the beginning of the lab session. The quiz will be based on some of the material shown below. 1. A student performed a titration on a 5.00 mL sample of an unknown HCl solution, using 10.90 mL of 0.09345 M NaOH from a buret and phenolphthalein indicator. What was the concentration of the unknown HCI? Use the correct number of sign ificant figures. 2. Another student designed a procedure to determine the...
An empty graduated cylinder weighs 56.90 g. A student puts 24.6 mL of an unknown liquid into the cylinder and the mass of the cylinder plus the liquid equals 98.47 g. What is the density of the unknown liquid (in g/mL)?
10. a) Report the volume (in mL) of liquid inside the graduated cylinder by reading the bottom of the meniscus (curved surface). 36.5 mL . b) What is the mass (in grams) of the liquid (d = 21.7 dg/ce) inside 881 the 50 mL graduated cylinder? de 88.188 g A ?g 50 mL graduated cylinder c) If all of the liquid inside the graduated cylinder was poured into the glass cup, what will the combined mass (in g) of both...
A student is given a sample of unknown liquid and she collects the following information at 25°C. mass of an empty graduated cylinder:65.26 g mass of the graduated cylinder containing 20.1 ml of the liquid is 78.31g.What is the density of the liquid? The literature value of the density of this liquid is 0.655 g/mL at 25°C what is the percent error in the students measurement ?
4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value. Explain your answer in clear and correct English. 16 LABORATORY EXPERIMENTS IN GENERAL CHEMISTRY ed in question 4...
In the lab, a student fills a dry 50 mL graduated cylinder with 30.0 mL of water. The mass of the water in the graduated cylinder was 30.743 grams at 25°C. What is the true volume of the water measured in the graduated cylinder? The density of water at 25°C is 0.99707 g/mL.
The given graduated cylinder is calibrated in milliliters (mL). Determine the volume of liquid in the graduated cylinder and report it to the correct number of significant figures. 50 பொற்ப volume: xid mL 40 TOOLS x100 30 20
I need the density (g/mL) for the water column and the isopropyl
alcohol column. With math shown and included please! The question
requires me to show work. If possible, I would also like the
percent error's (with work shown) of the water and isopropyl
alcohol columns. Thank you!
Part 1: Volume and Density Measurements (Liquid) 1 Gather the graduated cylinder, distilled water, short stem pipet, and isopropyl alcohol. 2 Place the clean, dry, 25 ml graduated cylinder on the tared...
