Chemistry question FIND THE MASS of 4.82 mole K2C2O4 ...the trouble is that I dont know if I have density or volume here!

You are looking for MASS so you won't need density or volume for this question.

You are given: 4.82 mole K2C2O4

Seking: mass = grams

Converting:

mole K2C2O4 x molar mass of K2C2O4 = mass of K2C2O4

Hope that helps.

you might want to post this question on the pre-nursing thread (https://allnurses.com/forums/f198/). i was a chemistry major, but it was so long ago i can't remember how to do this problem. chemistry weblinks for students are listed here on allnurses: https://allnurses.com/forums/2933150-post52.html

you've got 1 mole of the substance. you can find the molar mass of each atom on the periodic table. just add up the masses. be sure to account for subscripts (e.g. there are TWO hydrogens and ONE oxygen in H2O)

example:

mass of 1 mol of carbon = 1 mol * 12 g/mol = 12g
