Ritmeks

The mass of oxygen that reacted with the iron is 0.3g

The chemist burns 0.8g of iron in oxygen

the iron reacts to form 1.1g of iron oxide

Therefore the mass of oxygen can be calculated by subtracting the mass of iron in oxygen from the mass of iron

= 1.1 - 0.8

= 0.3g

Hence the mass of oxygen that reacted with the iron is 0.3g
