How do i calculate the mass in grams of 8.0 mol lead oxide (pbo)?

Mass = 1785.6 g

Explanation:

Given data:

Moles of lead oxide = 8 mol

Mass in grams = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Mass = number of moles × molar mass

Molar mass of PbO = 223.2 g/mol

Now we will put the values.

Mass = 8 mol ×  223.2 g/mol

Mass = 1785.6 g

Thus 8 moles of lead oxide have 1785.6 grams.

fe 55.85 g/mol and h2o 18.02 g/mol.
