Answer:
4.5moles
Explanation:
Given parameters:
Mass of Na₃P = ?
Unknown:
Number of moles = ?
Solution;
The number of moles in a given substance can be derived from the expression below;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of Na₃P = 3(23) + 31 = 100g/mol
Number of moles = [tex]\frac{450}{100}[/tex] = 4.5moles
