1. Ammonium carbonate decomposes upon heating according to the following balanced equation: 

(NH₄)2CO₃(s)→2NH₃(g)+CO₂(g)+H₂O(g)

Calculate the total volume of gas produced at 24.0 °C and 1.05 atm by the complete decomposition of 11.9 gof ammonium carbonate. Volume in Liters

2. What volume of air contains 10.4 g of oxygen gas at 273 K and 1.00 atm? Express your answer using two significant figures.

GasPercent by volume (%)Nitrogen (N2) 78% Oxygen (O2)21% Argon (Ar)0.9% Carbon dioxide (CO2)0.04%

3. What is the partial pressure of argon, PAr, in the flask?

A 1.00 L flask is filled with 1.45 g of argon at 25 °C. A sample of ethane vapor is added to the same flask until the total pressure is 1.100 atm.

4. a.What volume of H2 gas (in L), measured at 758 mmHg and 90 °C, is required to synthesize 28.6 g  CH3OH?

CH3OH can be synthesized by the following reaction:

CO(g)+2H2(g)→CH3OH(g)

b. How many liters of CO gas, measured under the same conditions, is required?
