Question

calculate the amount of carbon in the molecule

Answer 1

425 mL of 0.645 M magnesium bicarbonate (aq)

Answer 2

so I know the chemical formula is Mg2(HCO3)2

Answer 3

since it says that the number of moles is 0.645 I would multiply by the molar mass of carbon times 2 because there are 2 carbon atoms

Answer 4

0.645*2*12=15.48 is what I get but my answer is incorrect. What am I doing wrong?
