Answer

The molar mass for $FeSO_4$ is equal to 151.91 g

Work Step by Step

1. Identify the molar mass for each element in this compound: $Fe: 55.85$ g $S: 32.06$ g $O: 16.00$ g 2. Multiply each one of them by their respective subscript number: $Fe: 55.85$ g $S: 32.06$ g $O: 16.00$ g * 4 = 64.00 g 3. Calculate the total sum of these values: $55.85g + 32.06g + 64.00g = 151.91g$
