Question

Problem 2.67 A gem has a mass of 5.00 g. When the gem is placed in a graduated cylinder containing 10.00 mL of water, the water level rises to 14.45 mL. Express the density in grams per milliliter to three significant figures. Answer: Density = mass/volume Density = 5.00 g / (14.45 mL - 10.00 mL) Density = 5.00 g / 4.45 mL Density = 1.124 g/mL Part D A 3.50 mL sample of medication has a mass of 6.85 g. Express the density in grams per milliliter to three significant figures. Answer: Density = mass/volume Density = 6.85 g / 3.50 mL Density = 1.96 g/mL

          Problem 2.67
A gem has a mass of 5.00 g. When the gem is placed in a graduated cylinder containing 10.00 mL of water, the water level rises to 14.45 mL. Express the density in grams per milliliter to three significant figures.

Answer:
Density = mass/volume
Density = 5.00 g / (14.45 mL - 10.00 mL)
Density = 5.00 g / 4.45 mL
Density = 1.124 g/mL

Part D
A 3.50 mL sample of medication has a mass of 6.85 g. Express the density in grams per milliliter to three significant figures.

Answer:
Density = mass/volume
Density = 6.85 g / 3.50 mL
Density = 1.96 g/mL
