Answer :
Answer: The moles of weak acid in the solution are [tex]2.84\times 10^{-3}[/tex] moles
Explanation:
To calculate the number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
We are given:
Given mass of weak acid = 0.478 g
Molar mass of weak acid = 168.45 g/mol
Putting values in above equation, we get:
[tex]\text{Moles of weak acid}=\frac{0.478g}{168.45g/mol}=2.84\times 10^{-3}mol[/tex]
Hence, the moles of weak acid in the solution are [tex]2.84\times 10^{-3}[/tex] moles
