Question

30.00 grams of H3PO4

Answer 1

Number of moles = 0.31 mol

Step-by-step explanation:

Given data:

Mass of H₃PO₄ = 30.0 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of H₃PO₄ = 98 g/mol

Number of moles = 30.0 g / 98 g/mol

Number of moles = 0.31 mol
