Question

What is the mass, in grams, of 0.00948\,\text {mol}0.00948mol0, point, 00948, start text, m, o, l, end text of phosphoric acid?

Answer 1

m = 0.929 grams

Step-by-step explanation:

We have,

Number of moles of phosphoric acid is 0.00948

It is required to find the mass of phosphoric acid.

The number of moles in a given molecule is given by :

`n=(m)/(M)`

m is mass and M is molecular mass

The molecular formula of phosphoric acid is
`H_3PO_4`. Its molecular mass is :

`M=3* 1+31+16* 4=98\ g/mol`

So,

`m=n* M\\\\m=0.00948\ mol* 98\ g/mol\\\\m=0.929\ g`

So, the mass of phosphoric acid is 0.929 grams.
