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. To find the kilograms of solvent, we take our density of water and multiply it by the volume of water. So our density of water, we can look that up, and that's 1 gram per ML times the amount in volume of water. 300 MLS MLS cancel.
