Answer:
79.844 g.
Explanation:
First we are going to calculate the molar mass of
The molar mass of Fe is this means that 1 mol of Fe has a mass of 55.845 g.
The molar mass of O is this means that 1 mol of O has a mass of 15.999 g
To calculate the molar mass of we calculate the following number :
This means that 1 mol of has a mass of 159.687 g.
Finally, in 0.500 mol of we have
There are 79.844 g of in 0.500 mol of
