Question

A dentist is using an oral rinse that consists of a 9.76 x 10-2 mol/L sodium fluoride solution. Calculate the mass of sodium fluoride required to prepare a 850 mL solution of this concentration

Answer 1

Answer:

3.48 g NaF

Explanation:

Dimensional Analysis:

$\frac{(9.76*10^{-2})mol NaF}{1 L} * \frac{1L}{1000 mL} * \frac{41.99gNaF}{1 mol NaF} * 850 mL$

Answer (Simplifying the Expression Above):

3.48 g NaF
