Best ResponseYou've already chosen the best response.1not quite. if we wanted to know how much gold was in 83.0 grams of slyaniate, then yes, your approach would work, but the question wants to know how much sylvaniate has 83.0 g of gold

Best ResponseYou've already chosen the best response.1***Wouldn't it be 0.28 times 83? *** no, it would be 0.28 * unknown amount of mineral = 83 g pure gold or 0.28 x= 83 solve for x this will give the same answer as using proportions / ratios
