Sagot :
Answer: The mass of acetic acid that will be consumed is 1.512 g.
Explanation:
Molarity is defined as the moles of solute present per liter of the solution.
The formula used to calculate the molarity of the solution is:
[tex]\text{Molarity}=\frac{\text{Number of moles of solute}}{\text{Volume of solution (in L)}}[/tex]
OR
[tex]\text{Molarity}=\frac{\text{Given mass of solute }\times 1000}{\text{Molar mass of solute }\times \text{Volume of solution (in mL)}}[/tex] ......(1)
Given values:
Molarity of acetic acid = 0.84 M
Volume of solution = 30 mL
Molar mass of acetic acid = 60 g/mol
Plugging values in equation 1:
[tex]0.84=\frac{\text{Mass of acetic acid }\times 1000}{60 \times 30}\\\\\text{Mass of acetic acid}=\frac{0.84 \times 60\times 30}{1000}\\\\\text{Mass of acetic acid}=1.512 g[/tex]
Hence, the mass of acetic acid that will be consumed is 1.512 g.
