Answer:
0.929g
Explanation:
The following were obtained from the question.
Number of mole of phosphoric acid (H3PO4) = 0.00948mol.
Mass of H3PO4 =?
The mass in grams of phosphoric acid (H3PO4) can be obtained as follow:
Number of mole of H3PO4 = 0.00948mol.
Molar Mass of H3PO4 = (3x1) + 31 + (16x4) = 3 + 31 + 64 = 98g/mol
Mass of H3PO4 =?
Mass = number of mole x molar Mass
Mass of H3PO4 = 0.00948 x 98
Mass of H3PO4 = 0.929g
Answer:
[tex]m = 0.929\,g[/tex]
Explanation:
The formula for the phosphoric acid is [tex]H_{3}PO_{4}[/tex], whose molecular weight is [tex]97.994\,\frac{g}{mol}[/tex]. The mass in grams of the sample is computed afterwards:
[tex]m = (0.00948\,mole)\cdot (97.994\,\frac{g}{mol} )[/tex]
[tex]m = 0.929\,g[/tex]
