In the lab, a student fills a dry 100 mL graduated cylinder with 75.0 mL of water. The mass of the water in the graduated cylinder was 75.595 grams at 25°C. What is the true volume of the water measured in the graduated cylinder? The density of water at 25°C is 0.99707 g/mL.

The volume of the water that is filled in the graduated cylinder is calculated by dividing the given mass of the water by its density. That is,

    V = m / D

where V is volume, m is mass, and D is density. Substituting the known values,
   
    V = (75.595 grams) / (0.99707 g/mL) = 75.82 mL

Answer: 75.82 mL

Answer:

75.82 mL

Explanation:

We are given that

Volume of graduated cylinder=100 mL

Volume of water in graduated cylinder=75 mL

Temperature=[tex]25^{\circ}[/tex]

Mass of water in the graduated cylinder=75.595 g

Density of water=[tex]0.99707 g/mL[/tex]

We have to find the true volume of the water.

We know that density =[tex]\frac{mass}{volume}[/tex]

Substitute the values in the given formula

[tex]0.99707=\frac{75.595}{volume}[/tex]

[tex]Volume=\frac{75.595}{0.99707}=75.82 mL[/tex]

Hence, the volume of water=75.82 mL.
