Question

A lead fishing weight contains 0.12 mol of lead atoms. what is its mass?

Answer 1

.12 mol * 207.2 g/mol = 24.86g

Answer 2

24.86 g

Step-by-step explanation:

To answer this problem we need to look up the atomic weight of lead in the periodic table: 207.2.

With that information we know that 1 mol of lead weighs 207.2 grams, so we can calculate the weight of 0.12 mol of lead:

`0.12mol*(207.2g)/(1mol) =24.86g`

So the mass of the fishing weight is 24.86 g
