Answer:

Number of moles = 0.328 moles.

Explanation:

Given the following data;

Mass = 5.590 g

Molar mass = 17.030 g/mol

To find the number of moles;

[tex] Number \; of \; moles = \frac {mass}{molar mass} [/tex]

Substituting into the equation, we have

[tex] Number \; of \; moles = \frac {5.590}{17.030} [/tex]

Number of moles = 0.328 moles.
