First, find out the total mass of aspirin she took. Then, find the number of mole by dividing that mass by the molar mass.

OpenStudy (wolfe8):

Well, one tablet is 325mg and she took four doses; 2 every dose.

OpenStudy (wolfe8):

Notice that each dose has 2 pills :)

OpenStudy (wolfe8):

Um no. 4 doses where there are 2 pills in each dose. So...?

OpenStudy (wolfe8):

|dw:1389848721426:dw| and you have 4 doses.

OpenStudy (wolfe8):

Right, and we know one pill has 325 mg of the substance.

OpenStudy (wolfe8):

Yes, but be careful with the mili. When calculating moles, always use grams. So now you divide it by the molar mass.

OpenStudy (wolfe8):

Close. Be sure to convert mg to g first since the unit for mole is g/mol

OpenStudy (wolfe8):

Yes

OpenStudy (wolfe8):

OpenStudy (wolfe8):
