Molar C6H12O6 = 180.15 g/mol
180.15 g -------------- 6.02x10²³ molecules
?? g ------------------- 3.5x10²² molecules
( 3.5x10²²) x 180.15 / 6.02x10²³ =
=> 10.47 g
Answer:
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:

Explanation:
Step 1: Carbon and oxygen react to form carbon monoxide:
..[1]
Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:
..[2]
The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide can be obtained by :
3 × [1] + 2 × [2]

CO gas will gas cancel out form both sides ans we will get the net chemical equation:

According to reaction, 2 moles of ferric oxide reacts with 6 moles of carbon and 3 moles of oxygen gas to give 4 moles of iron and 6 moles pf carbon dioxide gas.
I think the answer is C I think that bc I added 3 and the 2 which made it H5 and than multipled the 3 and the 2 which made it C6 than Cl
