Chapter 0.6, Problem 27E

To determine

To calculate: The percent of glucose in pure solution.

Answer to Problem 27E

The percent of glucose in pure solution is $5\%$ .

Explanation of Solution

Given information:

When 6 milliliters of glucose is dissolved in 120 milliliters of pure solution, a glucose solution is prepared.

Formula used:

Percent proportion is ratio of amount and base is same as percent to 100.

To convert percentage to fraction divide the number by 100.

Calculation:

It is provided that when 6 milliliters of glucose is dissolved in 120 milliliters of pure solution, a glucose solution is prepared.

Let x percent of glucose is there in pure solution.

Recall that percent proportion is ratio of amount and base is same as percent to 100.

According to the question, amount of glucose divided by amount of pure solution is the desired percent,

  $\begin{array}{c}\frac{6}{120}=\frac{x}{100}\\ x=\frac{6\times 100}{120}\\ x=5\end{array}$

Thus, the percent of glucose in pure solution is $5\%$ .
