Question

Determine molar mass of (NH4)2HPO4

Answer 1

We have the next chemical formula

$(NH_4)_2HPO_4$

And we must determine the molar mass.

First, we must use the atomic mass of each element

- Hydrogen: 1.00794

- Nitrogen: 14.0067

- Oxygen: 15.9994

- Phosphorus: 30.973761

Then, we must replace the values of each atomical mass in the chemical formula

$(14.0067+1.00794\cdot4)\cdot2+1.00794+30.973761+15.9994\cdot4$

Finally, we must simplify the expression

$=132.056221\frac{g}{mol}$

ANSWER:

$=132.056221\frac{g}{mol}$
