Atotal of 1 mol iron oxide has a mass of

160 g

1 mole of a compound contains a mass equivalent to the relative formula mass of that particular compound.

the formula of iron oxide is Fe2O3

R.A.M of Iron = 56 , while that of oxygen is 16

RFM = (56 ×2) + (16 ×3)

       = 112 + 48

       = 160

Therefore, 1 mole of Iron oxide contains 160 g

the answer is a. co2, this would be colder than the : )

explanation:

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
