need some help
 
1. What is the mass of the solid NH4Cl formed when 73.0g of NH3 are
mixed with an equal mass of HCl? What is the volume of the gas
remaining, measured at 14*C and 752mmHg? What gas is it?

2. A piece of sodium metal reacts completely with water as follows:

2Na (s) + 2H2O --> 2NaOH (aq) +H2 (g)

The hydrogen gas generated is collected over water at 25*C. The volume
of the gas is 246mL measured at 1 atm. Calculate the number of grams
of sodium used in the reaction. (Vapor pressure of water at
25*C=0.0313 atm)

Thanks!

First answer these ...
1) what is homework ? :)
2) why would anyone help someone who hasn't tried to find the answer
or even thought about it ? :)

It was so much easier to blame it on Them. It was bleakly depressing to
think that They were Us. If it was Them, then nothing was anyones fault.
If it was Us, what did that make Me ? After all, Im one of Us. I must be.
Ive certainly never thought of myself as one of Them. No-one ever thinks
of themselves as one of Them. Were always one of Us. Its Them that do
the bad things. <=> Terry Pratchett. Jingo.

3) What is the email address of your instructor?
