Match the following.
-The mass of 1.22 moles of iron(II)nitrate

Question

Quizplus · Accepted Answer

To find the mass of 1.22 moles of iron(II) nitrate, we need to use the formula:

mass = moles x molar mass

The molar mass of iron(II) nitrate can be calculated by adding the atomic masses of its constituent atoms:

Fe = 55.85 g/mol 
N = 14.01 g/mol 
O = 16.00 g/mol

Molar mass of iron(II) nitrate = 55.85 + 2(14.01) + 6(16.00) = 179.89 g/mol

So, the mass of 1.22 moles of iron(II) nitrate = 1.22 x 179.89 = 219.16 g

Therefore, the best choice is B, which is closest to the calculated value.
