Question

type the correct answer in the box. a pharmacist works with a 1.75 m solution of sodium bromide (nabr) and water. the volume of the solution is 84.0 milliliters. if the pharmacist dilutes the solution to 1.00 m, what is the volume of the new solution? express your answer to three significant figures. the volume of the new solution is milliliters.

Explanation:

Step1: Identify the dilution formula

$M_1V_1 = M_2V_2$

Step2: Assign values

$M_1 = 1.75\ M$, $V_1=84.0\ mL$, $M_2 = 1.00\ M$

Step3: Solve for $V_2$

$V_2=\frac{M_1V_1}{M_2}=\frac{1.75\ M\times84.0\ mL}{1.00\ M}=147\ mL$

Answer:

147
