my school why now this explanation is not details but thank God im able to solve it okay here is it
16g of o2 ————— 32 Rmm of oxygen
x mol of co2 ————- 44 Rmm of co2
x = 44 * 16 / 32 = 704/ 32 = 22 grams of co2
we are ask to find the mole of co2 so
no of mole = mass / molar mass = 22 / 44 which is the rmm of co2
no of mole = 0.5 mol
how i get the rmm of co2 = 12 + 16x 2 = 44g
