number of moles in 5.64kg of barium

Answer 1

To calculate the number of moles in 5.64kg of barium, we need to divide the mass by the molar mass of barium.

The molar mass of Barium (Ba) is 137.33 g/mol.

First, we need to convert the mass from kg to g:

5.64 kg = 5640 g

Next, we divide the mass by the molar mass:

5640 g / 137.33 g/mol = 41.072 mol

Therefore, there are 41.072 moles in 5.64 kg of barium.
