Calculate the mass in grams present in 0.95 mole of sodium hydrogen trioxocarbonate(iv)

2 answers

So the molar mass of Na2(CO3) is 84g/mol..check that.

mass is .95 times the molar mass.
Why don't you use sodium hydrogen carbonate for the name.
Bob Pursley gave you the right procedure and the right numbers. That 84 should be for NaHCO3.
