Answer:
25.9 g
Explanation:
Given that,
No of moles of calcium phosphate, [tex]n=9.3\times 10^{-2}[/tex]
We need to find how many grams of calcium phosphate has this much of no of moles.
Mass divided by molar mass is equal to the no of moles on a molecule.
The molar mass of calcium phosphate is 310.18 g/mol
Using the concept of no of moles as follows :
[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=9.3\times 10^{-2}\times 310.18\\\\m=28.84\ g[/tex]
Out of given options, option (a) i.e. 25.9 g is the correct answer.
