First convert 12.0g of Na to moles using the grams to moles conversation and you get about. 5219 moles (I didn't use significant figures). Divide that number by 3 because that is the coefficient of Na and you will get about. 17398 moles, which is how many moles are in 1. Since Al has a coefficient of 1,.17398 woild be your final answer
