Final answer:
The formula mass of ammonium sulfite (NH4)2SO3 is calculated by adding up the atomic masses of all atoms in the formula, and based on our calculation, none of the provided options seem correct.
Explanation:
The formula mass of ammonium sulfite, (NH4)2SO3, is calculated by adding up the atomic masses of all the atoms present in the formula. This includes two nitrogen atoms, eight hydrogen atoms, one sulfur atom, and three oxygen atoms. In our case, this comes to: (2 * 14.01 amu) + (8 * 1.01 amu) + (1 * 32.06 amu) + (3 * 16.00 amu) = 68.04 + 8.08 + 32.06 + 48.00 = 156.18 amu. The given options seem incorrect based on the calculation. Kindly verify the options once again.
