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

3.48 g NaF

Step-by-step explanation:

Dimensional Analysis:

`((9.76*10^(-2))mol NaF)/(1 L) * (1L)/(1000 mL) * (41.99gNaF)/(1 mol NaF) * 850 mL`

Answer (Simplifying the Expression Above):

3.48 g NaF
