Question

The equivalent weight of CaCO3 is (molar mass of
CaCO3 = Mg mol-1)
(1) M
(2) M/4
(3) M/3
(4) M2​

Answer 1

Answer:

M/2

Explanation:

equivalent wt. = molar mass ÷ n- factor

n factor of CaCO3 is 2

molar mass= M

so equivalent wt. = M/2

Answer 2

Molar mass relates the mass of a substance to the moles of the substance (g/mol). The mole in chemistry is sometimes called the chemist's ''dozen'' because it's a counting unit like a dozen. Just like there are 12 donuts in a dozen, there is 6.02 x 1023 atoms or molecules in a mole. Molar mass tells chemists how many grams of a substance are needed for 6.02 x 1023 atoms or molecules.

Answer and Explanation:

The molar mass of calcium carbonate is 100.086g/mol.

The first step of determining the molar mass is to determine the chemical formula of calcium...
