Question

Convert to moles: 100.0g Ca3(PO4)2

Answer 1

Answer:

0.322 moles

Explanation:

Given Mass, m = 100 g

The molar mass of Ca₃(PO₄)₂

Ca₃(PO₄)₂ = (3 x 40.08) + (2 x 30.97) + (8 x 16.00)

M = 310.18 g/mol

Let there are n number of moles,

n = given mass/ molar mass

$n=\dfrac{100 }{310.18 }\\\\n=0.322\ mol$

So, there are 0.322 moles.
