You carefully weigh out 19.00 of powder and add it to 76.95 of solution. You notice bubbles as a reaction takes place. You then weigh the resulting solution and find that it has a mass of 88.16 . The relevant equation is
CaCO3+2HCl > H2O + CO2 + CaCl2
Assuming no other reactions take place, what mass of was produced in this reaction?
I have no idea how to attempt to solve this problem, i tried getting moles of carbon but I'm lost. Help please.

oops...* Assuming no other rxn's what mass of CO2 was produced in this rxn?

Do you not believe in units? Is that 19.00g, 76.95g, and 88.16g? If so, then
19.00g + 76.95g on the left.
Mass H2O and CaCl2 on the right = 88.16g. So the difference must be the mass CO2 on the right.
