Lead has a density of 11.3 g/cm3 and a mass of 282.5 g. What is its volume? a. 2.5 cm3 c. 250 cm3 b. 25 cm3 d. 2500 cm3
Answer : The correct option is, (b) \(25cm^3\)
Solution : Given,
Mass of lead = 282.5 g
Density of lead = \(11.3g/cm^3\)
Formula used :
\(\text{Density of lead}=\frac{\text{Mass of lead}}{\text{Volume of lead}}\)
Now put all the given values in this formula, we get the volume of lead.
\(11.3g/cm^3=\frac{282.5g}{\text{Volume of lead}}\)
\(\text{Volume of lead}=25cm^3\)
Therefore, the volume of lead is, \(25cm^3\)
