Density of Planets and Moons Lab Objectives: In this lab you will learn: Part 1 – What density is, and how to experimentally determine it Part 2 – To calculate various physical quantities for the planet Mercury Part 3 – Group major solar system bodies by density Part 1. DENSITY Definition – Density =mass / volume. Symbolically, we write this as , where 1) ρ (the Greek letter “rho”) is the density, 2) m is mass, and 3) V is...
I need help with lab this week. I have posted theory and procedures to the lab. The questions with ????????? are the ones I need help with. Please Help!! Thank you Theory Density is defined as mass per unit volume that has a metric unit of kg per cubic meter. Grams per cubic centimeter i.e. g/cm3 actually is widely used as the unit of density. The densities for objects with regular shapes are easily to be determined. For objects with...
A stainless steel ball (radius rsphere = 0.3175 cm, density ρsphere = 7.866 g/cm3) falls through a viscous fluid (density ρfluid = 1.2 g/cm3) and quickly reaches terminal speed v. You measure the ball’s position as a function of time to find v. The ball is at positions y = 10 cm at time 2.402 and at position y = 5 cm at time 3.26. Calculate the viscosity η of the fluid in units of poise = g/(cm-s), using your...
The density of a sample of metal was measured to be 10.50 g/cm^3
. An X-ray diffraction experiment measures the edge of a
face-centered cubic cell as 408.0 pm . What is the atomic mass of
the metal? Express the atomic mass to one decimal place and include
the appropriate units.

At Home Lab: Density Introduction: Density I am sure you have carried two full grocery bags to your car and noticed one bag being much heavier. Since the two bags are the same size and one bag has more mass, the heavier bag must be more dense. A non-scientific definition for density is how tightly packed something is. Supplies: • 100ml Graduated Cylinder • Corn Syrup • Vegetable oil • Tap Water • Food Coloring or Universal Indicator Reasoning: The...
Lab Exercise IB Examples: 1000 is expressed as 1 x 10) (1000 is greater than (1000 is greater than 1, so the exponent is positive) tion of 1. so the exponent is negative) 0.001 is expressed as 1 x 10-3 (0,001 is a fraction of 1 Note: you cannot just count the number of Os, you ne need to count the number of places th decimal moves to make the coefficient be greater Now lets combine all 3 rules: 0.00000000000308...
What is the life span of a lab mouse? You measured the following life spans (in days) for a certain standard inbred laboratory strain. 1025, 821.419, 771, 486, 1017, 657, 1151, 700, 752, 807, 924, 703, 1035 You may assume for the following questions that the distribution of life span is normal. (a) Calculate the sample mean x. 804.8571 b) Calculate the sample standard deviation s.210.9385 (c) Calculate the critical value tfor a 87 percent two-sided confidence interval. 1.1616X (a)...
1-) Silica gel has a bulk density of about 0.3 g/cm3, so 15 g would occupy a volume of 45-50 cm3 (45-50 mL). This quantity is called the: 2-) You are carrying out a chromatographic separation on a 15 mg sample using 6.5 g of silica gel in your column. If you aim for a column height of 10 cm of silica gel, what is the inside diameter of the necessary chromatography column in units of cm? 3-) Consider the...
Suppose you have 150. mL of a substance with a density of 42.0 g/dm and want to determine the mass of the substance. The calculation can be broken down into three steps. First, convert the volume from milliliters to liters. Then, convert the volume from liters to cubic decimeters. Finally, determine the mass of the sample in grams. Show the unit analysis by placing the correct components into the unit-factor slots. The question marks (?) represent the answer to the...
