Question

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

1.) What is the volume of this sample (in mL)?

2.)What mass (in grams) of this sample would have a volume of 76.5 mL?

Answer 1

The relation between density, mass and volume is

`Density = (Mass)/(Volume)`

1) to calculate = volume

given:

Density = 0.0915 g/ mL

mass = 17.7 grams

formula used:

`Density = (Mass)/(Volume)`

Thus

Volume
`Volume = (Mass)/(Density) = (17.7 g)/(0.915 (g)/(mL) )  = 193.44 mL`

Answer: 193.44 mL

2) the mass of sample will be

`mass = density X volume = 0.0915(g)/(mL) X 76.5 mL = 6.99 = 7 g`

Answer: 7 g
