Question

CHW 1 (Ch. 1.3) Problem 2.70 An epony carving nas a mass or z g ana a voume of 192 cm Express the density in grams per milliliter to three significant figures. g/mL Submit Request Answer Part B A 14.3-cm sample of tin has a mass of 0.104 kg Express the density in grams per milliliter to three significant figures. g/mL Submit Part C A bottle of acetone (fingernall poläish remover) contains 43.5 mL of acetone with a mass of 55.0 g. Express the density in grams per milliliter to three significant figures. g/mL Submit Provide Feedback

Explanation / Answer

Part : A:

density = mass / volume

density = 225 g / 192 mL = 1.17 g/mL

Therefore, density = 1.17 g/mL

part B: density = mass / volume

mass = 0.104 kg = 104 g

density = 104 g / 14.3 mL = 7.27 g/mL

Therefore, density = 7.27 g/mL

Part C: density = mass / volume

density = 55.0 g / 43.5 mL = 1.26 g/mL

Therefore, density = 1.26 g/mL
