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}}* 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}}* 100


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

Hence, the mass of solution is 4.86 grams.
