a retro calculation of the amount of Ni(Nh3)6Cl2 that is needed if 20mL of 0.10M HCl are used to neutralize ammonia. The number I got was 0.07727 g.
So then I measured out Ni(Nh3)6Cl2 ..about 0.0776g.
Molarity of the HCl I used was 0.104MVolume of HCl to neautralize was 18.8 mL
How do I find the mols of HCl?, (It says in the lab mols HCl = NH3) Mass of NH3, and % NH3 in product?
Three gases (8.00 g of methane, 18.0 g of ethane, and an unknown amount of propane were added to the same 10.0-L container. At 23.0 degrees C, the total pressure in the container is 4.50 atm. Calculate the partial pressure of each gas in the conta..
