Question

How many grams of solution must contain 1.7 g of nh4cl to make a 35% nh4cl solution by mass?

Answer 1

Answer: The mass of solution of $NH_4Cl$ is 4.86 grams.

Explanation:

In $NH_4Cl$, there are 1 nitrogen atom , 4 hydrogen atoms. and 1 chlorine atom.

To calculate the mass percent of element in a given compound, we use the formula:

$\text{percent by mass}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

Percent by mass of solution = 35%

Mass of solute $NH_4Cl$ = 1.7 gram

Mass of solution  = ?

Putting values in above equation, we get:

$35=\frac{1.7}{\text{Mass of solution}}\times 100$

${\text{Mass of solution}}=4.86g$

Hence, the mass of solution is 4.86 grams.
