Question

how many moles of 5g calcium

Answer 1

Mass = 5g

To calculate the number of moles, we use the formula Number of moles = Mass ÷ Molar mass.

First, we find the molar mass of calcium from the periodic table.

Calcium's molar mass = 40g/mol

Now we can calculate the number of moles with the formula given.

5g ÷ 40g/mol = 0.125 moles

Therefore, there are 0.125 moles in 5g of calcium.
