Answer:

M_{acid}=26.804g/mol

Explanation:

Hello,

In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:

n_{acid}=n_{NaOH}

By knowing the volume and the concentration of the NaOH, one obtains:

n_{acid}=0.05238L*0.396\frac{mol}{L}=0.0207mol

Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:

M_{acid}=\frac{m_{acid}}{n_{acid}}=\frac{0.556g}{0.0207mol}=26.804g/mol

Best regards.

What is the charge on an ion that has an atomic number of 16 and contains 14e-?
lora16 [44]
The answer would be 2+ since the atomic number represents how many protons are in the element. In this case, there are 16 protons, but only 14 electrons, which means there are an additional 2 protons, hence the 2+ charge on the ion.
