Stomach acid is essentially 0.10 M HCl. An active ingredient found in a number of popular antacids is CaCO3. Calculate the number of grams of CaCO3 needed to exactly react with 250 mL of stomach acid. CaCO3(s)+ 2HCl(aq)= CO2(g)+ CaCl2(aq)+ H20(l)

Chemistry
The answer is 1.3 grams of CaCO3. I am not getting that by multiplying mols CaCO3 x molar mass CaCO3.

after you multiple the top by 3 and the bottom by 3 you have to either multiple the top by a negative or the bottom so that when adding the x's they cancel out to equal 0. then add the y's and the other numbers. then divide to find y. heres the first step for starters ...

ok so for this you do x/3=x/5-2 you multiple both sides by 3 so you have x=x/15 -6 then go on from there

um i don't think so if you add 4 to the right side you get 2x=4x+1 then minus the 4x so that gets -2x=1 then divide by -2 which would be x=-1/2 i think thats it:)
