Question

A student obtained a clean, dry, glass-stoppered flask. He weighed the flask stopper and found the total mass to be 32.634g. He then filled the flask with water, weighed again, and obtained a mass of 59.479g. At the temperature of the water, he found that its density was 0.9973 g/mL.a.) What was the mass of the water? (show work)b.) What was the volume of the water? (Show work)c.) What was the volume of the flask? (show work)

Answer 1

Answer :

The mass of water is, 26.845 g

The volume of water is, 26.92 mL

The volume of flask is, 26.92 mL

Explanation : Given,

Mass of flask stopper = 32.634 g

Mass of water and flask stopper = 59.479 g

Density of water = 0.9973 g/mL

First we have to calculate the mass of water.

Mass of water = Mass of water and flask stopper - Mass of flask stopper

Mass of water = 59.479 g - 32.634 g

Mass of water = 26.845 g

Thus, the mass of water is, 26.845 g

Now we have to calculate the volume of water.

$\text{Volume of water}=\frac{\text{Mass of water}}{\text{Density of water}}$

$\text{Volume of water}=\frac{26.845g}{0.9973g/mL}$

$\text{Volume of water}=26.92mL$

Thus, the volume of water is, 26.92 mL

Now we have to calculate the volume of flask.

Volume of flask = Volume of water = 26.92 mL
