Answer:

2.5M

Explanation:

First calculate the gram-formula mass of CaCO3 (add up the mass of each element in the compound)

40.1 + 12.01 + 16(3) = 100.11

Now use the mole calculation equation on Table T and plug in the numbers

(Keep in mind that 25 is the given mass)

25/100.11 = 2.497 or 2.5M
