Correct Answer: Option C

Explanation

Given:

V = ? ,  C = 0.100M,   m = 5g   

Molar mass, M of NaNO\(_3\) = 23 + 14 + (16 X 3) = 85 g/mol

Number of moles, n = \(\frac{mass}{Molar Mass}\)

                                =  \(\frac{5}{85}\)

                             n = 0.0588 mole

Recall that            n = \(\frac{CV}{1000}\) 

                             n = CV (looking through the options, no need including the 1000 since the answer was left in Litres)

                            V = \(\frac{n}{C}\)

                            V =   \(\frac{0.0588}{0.100}\)

                            V =  0.588 Litres
