Calculate the volume (in cm³) of 38.5 grams of platinum if the density of platinum is 21.5 g/cm³. Give your answer to 2 decimal
Gennadij [26K]

Answer:

\boxed {\boxed {\sf v\approx  1.79 \ cm^3}}

Explanation:

The formula of density is:

d=\frac{m}{v}

If the formula is rearranged for volume, it becomes:

v=\frac{m}{d}

The mass of the platinum is 38.5 grams.

The density is 21.5 grams per cubic centimeter.

m=38.5 \ g \\d= 21.5 \ g/cm^3

Substitute the values into the formula.

v=\frac{38.5 \ g}{ 21.5 \ g/cm^3}

Divide. Note that the grams (g) will cancel each other out.

v=1.79069767 \ cm^3

Round to 2 decimal places (hundredth place). The 0 in the thousandth place tells us to leave the 9 in the hundredth place.

v\approx  1.79 \ cm^3

The volume is about <u>1.79 cubic centimeters.</u>
