(The volume of a sphere with a radius r is V = (4/3) π r3; the density of gold is 19.3 g/cm3.) -answer in scientific notation (b) a cube of platinum of edge length 0.024 mm (density = 21.4 g/cm3).- answer in scientific notation (c) 66.9 mL of ethanol (density = 0.798 g/mL).- answer in scientific notation
A 15.00 g metal sphere was found to have a diameter of 1.85 cm. The volume of a sphere is V = (4/3)pir^3. Calculate the density of the sphere and assuming that the sphere is made out of one of the elements, aluminum, chromium, iron, lead, titanium or zinc, determine its composition. A 5581 gram irregular object made out of one of the metals in #6 raises the water level in a graduated cylinder from the 17.6 mL level to...
Calculate Density (g/cm^3) of the sphere. Show all work. Given: Volume = 15142 cm^3 +/- 0.243% or 15142 cm^3 +/- 37 cm^3 Beam Balance measurement of sphere: 24.0g +/- 0.1g Electronic balance measurement of the sphere: 23.7g +/- 0.1g
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...
A sphere has radius R = 12.3 measured in cm. What is the volume of this sphere measured in in3? (Hint: The volume of a sphere is given by V = 4 3 π R 3 .)
4) what volume (mL) of a 3.1% (by mass) chlorine solution (density= 1.15 g/mL) contains enough chlorine to raise the chlorine concentration of a 27000 gal swimming pool to 2.5 ppm (by mass). Assume a density of 1.00 g/mL for the pool water. (4 pts)

A solid metal sphere has a radius of 3.39 cm c m and a mass of 1.877 kg k g . What is the density of the metal in g/cm3 g / c m 3 ? (The volume of sphere is V=43πr3 V = 4 3 π r 3 .)
Error Propagation and Density of Materials I need you to finish the two columns(Don't worry about the third) in the table using the formulas in page one. Please show work 3) Use the Vernier caliper to measure the height, h, and the diameter, D, of the cylinder. Record h and D and their uncertainties, Ah and AD. 4) the graduated cylinder Use metal. the determine of to the volume how would you do this? Analysis The density of a sample...
To determine the volume of a sphere, you measure its diameter using a ruler an obtain a value of 15.2 mm for the diameter. Using this diameter, you convert the diameter to units of centimeters by dividing the radius by 10 mm/cm and then you divide the diameter by 2 to obtain the radius (r). You then use the equation V = 4/3rr to obtain the volume of the sphere. To determine the mass, you measure the mass on a...
