A chemist has a block of lead metal (density is 11.3 g/mL). The block weighs 2.10g. What is the volume if the lead block in mL?
mezya [45]

The volume of a block of lead metal that has a density of 11.3g/mL and weighs 2.10g is 0.186mL.

<h3>How to calculate volume?</h3>

The volume of a substance can be calculated by dividing the mass of the substance by its density. That is;

Volume = mass ÷ density

According to this question, a chemist has a block of lead metal (density is 11.3 g/mL). The block weighs 2.10g.

Volume = 2.10g ÷ 11.3g/mL

Volume = 0.186mL

Therefore, the volume of a block of lead metal that has a density of 11.3g/mL and weighs 2.10g is 0.186mL.
