So let's begin. Molecular weight of our nitric acid is simply calculated by adding up the atomic weights of each respective atom. So 1 gram/mol for H plus 14 grams/mol for N plus three times. Because we have a subscription of 316 grams per mole for O, gives you a molecular weight of 63 grams/mol for nitric acid. Now, to find the moles of nitric acid, we take our grams of nitric acid, divide that by our molecular weight grams cancel, moles goes on top, and we get zero point 73 moles of nitric acid. So finally, we have to find the kilograms of solvent.
