5. How many grams are in 0.52 moles of H3PO4?

Answer 1

50.96g

Step-by-step explanation:

Given parameters:

Number of moles of H₃PO₄ = 0.52moles

Unknown:

Mass of the compound = ?

Solution:

To find the mass of the compound:

Mass = number of moles x molar mass of H₃PO₄

Molar mass of H₃PO₄ = 3(1) + 31 + 4(16) = 98g/mol

Mass = 0.52 x 98 = 50.96g
