Answer:
The percent by mass of sodium chloride in the broth is 0.1875 %
Explanation:
Our first step is transforming the sodium chloride figure from mg to g
450mg x 1g/1000 mg= 0.45g
Now, we must calculate the percentage by using the following formula:
0.45g / 240g x 100= 0.1875%
Henceforth, we can conclude that the percentage by mass of sodium chloride in the broth is 0.1875%
