To calculate the molecular masses of the given compounds, we need to sum up the atomic masses of all the atoms present in each compound.
1. NICO3:
N = 14.01 g/mol
I = 126.90 g/mol
C = 12.01 g/mol
O = 16.00 g/mol (x3)
Molecular mass of NICO3 = 14.01 + 126.90 + 12.01 + (16.00 x 3) = 14.01 + 126.90 + 12.01 + 48.00 = 200.92 g/mol
2. POCl3:
P = 30.97 g/mol
O = 16.00 g/mol
Cl = 35.45 g/mol (x3)
Molecular mass of POCl3 = 30.97 + 16.00 + (35.45 x 3) = 30.97 + 16.00 + 106.35 = 153.32 g/mol
3. H2SO4:
H = 1.01 g/mol (x2)
S = 32.07 g/mol
O = 16.00 g/mol (x4)
Molecular mass of H2SO4 = (1.01 x 2) + 32.07 + (16.00 x 4) = 2.02 + 32.07 + 64.00 = 98.09 g/mol
Therefore, the molecular masses of NICO3, POCl3, and H2SO4 are 200.92 g/mol, 153.32 g/mol, and 98.09 g/mol, respectively.
