Posted by Dil on Tuesday, January 13, 2009 at 11:24pm.

Ive been trying to do my chemistry homework for the past few hours and I keep getting some of the questions wrong. These are the 2 questions i am having trouble with.

If 0.582 L of gaseous CO2 measured at STP dissolved in 920 mL of water is produced stoichiometrically according to the balanced equation in a reaction solution with a total volume of 1800 mL, what is the molarity (M) of Na+ produced?

Na2CO3(aq) + 2 HCl(aq) CO2(g) + 2 NaCl(aq) + H2O(l)

Molar Mass (g)
CO2 44.010
Na+ 22.989

Molar Volume (L)
22.400 at STP
Gas Constant

2.If 1.15 g of solid MnS and 800 mL of 0.0288 M aqueous HCl are reacted stoichiometrically according to the equation, how many mol of solid MnS remained?

MnS(s) + 2HCl(aq) H2S(g) + MnCl2(aq)
Molar Mass (g)
HCl 36.461
MnS 87.00

Molar Volume (L)
22.400 at STP
Gas Constant
