if they give moles of the reactants… u gotta convert it to grams of a product (be consistent if u have to pick)… then take the lowest amount and divide that into each value. this gives a whole number ratio.

Ex: three numbers after u convert are like .442, .884, and .442.
The smallest is .442 so divide and the small number u put into the formula. so it would be like 1 atom A, 2 atoms B, and 1 atom C.

AHHHH tomrrw
