Question

The density for gold is 19.3 g/cm3. What would be the mass of a 25 cm3 piece of gold?
A.
1.3g
B.
482.5g
C.
475g
D.
965g

Answer 1

To find the mass of a 25 cm³ piece of gold, you can use the formula:

\[
\text{Mass} = \text{Density} \times \text{Volume}
\]

Given that the density of gold is 19.3 g/cm³ and the volume is 25 cm³, you can plug in the values:

\[
\text{Mass} = 19.3 \, \text{g/cm}^3 \times 25 \, \text{cm}^3
\]
\[
\text{Mass} = 482.5 \, \text{g}
\]

So the mass of a 25 cm³ piece of gold is **482.5 g**.

The correct answer is **B. 482.5g**.
