oh, i'm sorry, i was not able to see your answer on my previous question right away. i was posting my questions first, hoping to have answers right a away even with just one of my posts. i'm sorry. and thank you, i'm now using what you told me. :)

Chemistry
a 15.00mL sample of NaOH was titrated to the stoichiometric point with 17.40mL of 0.2340M HCl. a) what is the molar concentration of the NaOH solution? b)calculate the grams of NaOH in the solution.

Chemistry
thank you. i'm just confused what to use to find the number of moles, when there's mass and other given. thanks for the help.

Chemistry
oh! is it right? i need to multiply the number of HCl to 1mol/6.022x10^(23)?

Chemistry
a)HCl + NaHCO3 -> NaCl + H2O + CO2 b)2HCl + CaCO3 -> CaCl2 + H2CO3 -> CaCl2 + H2O + CO2 c) Al2O3 + HCl -> AlCl3 + H2O + O2 hmmm a) 1mole b) 2moles 3) 1 ??

Chemistry
calculate the theoretical number of moles of HCl equivalent to 1 mole of a) NaHCO3 b)CaCO3 c)Al2O3

Chemistry
oh, you used the molarity to get the mole.. but i don't know what will i do with the 500mg and how to relate (3)and(4) to get the mass of NaHCO3.

Chemistry
i didn't round it off, because in our class we have a rule that we should not round off until we get the final answer. NaHCO3 + HCl -> NaCl + H2O + o2 0.040 L / 0.120 mole L = 0.33..

Chemistry
i got 0.01371516348 moles of HCl and then the molecular mass of NaHCO3 is 84.008.. how am i going to use these 2 to find the mass of NaHCO3? (sorry, i'm just confused)
