Question

A liquid sample, with a density of .0915 g/mL has a mass of 17.7 grams.

Answer 1

The relation between density, mass and volume is

$Density = \frac{Mass}{Volume}$

1) to calculate = volume

given:

Density = 0.0915 g/ mL

mass = 17.7 grams

formula used:

$Density = \frac{Mass}{Volume}$

Thus

Volume $Volume = \frac{Mass}{Density} = \frac{17.7 g}{0.915 \frac{g}{mL} } = 193.44 mL$

Answer: 193.44 mL

2) the mass of sample will be

$mass = density X volume = 0.0915\frac{g}{mL} X 76.5 mL = 6.99 = 7 g$

Answer: 7 g
