Answer:
m = 0.929 grams
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 :
[tex]n=\dfrac{m}{M}[/tex]
m is mass and M is molecular mass
The molecular formula of phosphoric acid is [tex]H_3PO_4[/tex]. Its molecular mass is :
[tex]M=3\times 1+31+16\times 4=98\ g/mol[/tex]
So,
[tex]m=n\times M\\\\m=0.00948\ mol\times 98\ g/mol\\\\m=0.929\ g[/tex]
So, the mass of phosphoric acid is 0.929 grams.
