How to solve these Chemistry problems?
You don't have to give the answers if you don't want to.. But if you could explain how to arrive to them, please do!!
1) A gas sample contains 16.0 g of CH4, 16.0 g of O2, 16.0 g of SO2, and 33.0 g of CO2. What is the total number of moles of gas in the sample?
2) How many formula units of sodium chloride are in 146 grams of sodium chloride?
3) Sulfur dioxide is reacted with excess oxygen in a contained chamber. The reaction is:
2SO2 (g) + O2 (g) → 2SO3 (g)
How much oxygen (as the element) is consumed if 14.6450 g of sulfur trioxide gas is produced?
4) Given the following unbalanced reaction:
H2CO3(aq) + CaCl2(aq) + MgCl2(aq) → CaMg(CO3)2(s) + HCl(aq)
Which reagent is limiting if 10.00 g of H2CO3, 10.00 g CaCl2, and 10.00 g of
MgCl2 are reacted?
