Question

The density of water at 40°c is 0.992 g/ml. what is the volume of 2.50 g of water at this temperature?

Answer 1

Answer:

the volume of 2.50 g of water at 40C is 2.52 ml

Explanation:

Given:

Density of water at 40 C = 0.992 g/ml

Mass of water = 2.50 g

To determine:

The volume of water

Formula:

Density of a substance is the mass occupied by the substance in a given volume

$Density = \frac{Mass}{Volume} \\\\Volume = \frac{Mass}{Density} =\frac{2.50g}{0.992 g/ml} = 2.52 ml$

Answer 2

To calculate for the volume of a substance, simply get the ratio of the mass and density. That is:

Volume = mass / density

 

Therefore by substitution:

Volume = 2.50 g / (0.992 g / mL)

Volume = 2.52 mL
