To find the moles of oxygen, we simply take our Molar concentration, multiply that by one liter of total solution and we get 0.000,264 moles of O two and 0.0055 moles for M two. Finally, we can use the moles, multiplying that by the molecular weight of each respective compound. That will give us the number in grams of each compound resolved within our system. So molecular weight of oxygen, which is 32 grams/mol multiplied by the moles, which is 0.00,134
moles, gets us oh, I'm sorry. I made a mistake here. This should be 0.00,264
moles.
