Calculate the percent composition (percent by mass of each element) of NH4Cl. Round to the nearest ONES place ((example: 12.34% = 12%))

Explanation:

Hello!

In this case, since the calculation of the percent composition of an element in a chemical compound is computing considering its atomic mass, subscript in the formula and molecular mass of the compound it is; for nitrogen, hydrogen and chlorine we have that ammonium chloride has a molar mass of 53.49 g/mol so the percent compositions are:

Best regards!

i'm pretty sure its b i might be wrong though!
