Chapter 15, Problem 6STP

Interpretation Introduction

Interpretation:

The volume of given sodium hydroxide solution is calculated.

Concept introduction:

Molarity equation can be used to calculate the volume of a given concentration of sodium hydroxide solution.

  $M_1{V}_1=M_2{V}_2$

  $V_1=\frac{M_2{V}_2}{M_1}$

Where,

  $M_1$ and $M_2$ are the molarity of solutions

  $V_1$ and $V_2$ are the volume of the solutions.

Answer to Problem 6STP

A

Explanation of Solution

Given:

  $M_1=2M$

  $M_2=0.800M$

  $V_2=150mL$

Substituting the values:

  $\begin{array}{c}{V}_1=\frac{0.8\times 150}{2}\\ =60mL\end{array}$

Conclusion

The mathematical calculations show that option A is correct and the remaining options are wrong.
