m(Fe2O3)=213 g
m(CO)=140 g
</span>_______________
<span>n(Fe2O3)=?
m(Fe)=?
n(Fe2O3)=?
n(CO)=?
n(CO2)=?
</span>
<span>n(Fe2O3)=m(Fe2O3) / M(Fe2O3)
n(Fe2O3)= 213 g / 159,7 gmol-1 = 1,33 mol
</span>
<span>n(CO)= m(CO) / M(CO)
n(CO)= 140 g / 28,01 gmol-1 = 4,99 mol</span>
Rock and sand are non-living. All organisms are living.
False because I think it’s supposed to be photoheteroterotrophs

Explanation:
The way you get this is by subtracting the mass which is 27 (I rounded this) by the atomic number which is 13 to get 14 neutrons.
