how many grams are in 2.35 moles of calcium carbonate?

Question

0.01175g/mol or 0.0235g/mol or 0.0588g/mol or 107g/mol

Answer 1

Calcium carbonate has 1 Ca atom, 1 C atom and 3 oxygen atoms. Add up the atomic weights for each. This is how many grams are in one mole of CaCO3.

To find how many grams are in 2.35 moles, set it up like this:

2.35 moles ( x grams CaCO3 / mole CaCO3)

your moles cancel and x is the value you added up for 1 Ca, 1 C and 3 O atoms (get atomic weights from periodic table). Plug in x and multiply by 2.35.

Answer 2

Atomic weights: Ca=40 C=12 O=16 CaCO3=100

2.35molCaCO3 x 100gCaCO3/1molCaCO3 = 235gCaCO3

Your question makes no sense. First, you ask for a number of grams, next you give possible answers in g/mol.
