Question

liquid benzene burns in oxygen according to 2 mole of benzene react wid 15 mole of oxygen gives 12 mole of carbon dioxide & 6 mole of water how many litre of o2 at stp are needed to complete thevcombution of 39 g of liquid benzene

Answer 1

2moles =156g of benzene, 156g of benzene =15moles of o2, wht about 39g of benzne Will oproduce howmany o2 mole, 39*15/156=3.75moles,1mol at stp =22.4litres wht a obout 3.75moles, 22.4*3.75=84litres
