Pls help i need pointsthe answer is
The molar mass of the following compounds in two decimal places are as follows:
- NH3: 17.04 g/mol
- Mg(OH)2: 58.33 g/mol
- Fe2O3: 159.70 g/mol
<h3>MOLAR MASS:</h3>
The molar mass of a compound is the sum of all the atomic masses of the elements that constitutes the compound.
According to this question, three compounds were given as follows: NH3, Mg(OH)2 and Fe2O3.
The atomic mass of the elements in this compounds are as follows:
- N = 14
- H = 1
- Mg = 24
- O = 16
- Fe = 56
- The molar mass of NH3 = 14 + 3 = 17g/mol
- The molar mass of Mg(OH)2 = 24 + 32 + 2 = 58g/mol
- The molar mass of Fe2O3 = 56(2) + 16(3) = 160g/mol
