Answer:
volume of gas=101.94L
Explanation:
Suppose given gas follows the ideality nature of gas
PV=nRT
n=35.8/44mol=0.814 mol
P=0.197atm
T=27.5C=300.5K
R=0.0821atm/mol/K
after putting all value we get,
V=101.94L
volume of gas=101.94L

Because it will just tell if the solution is acidic or basic, it won't tell the pH
CO2 is the emperical formula of carbon dioxide
Answer:
V = 22.41 L
Explanation:
Given data:
Mass of nitrogen = 14.0 g
Volume of gas at STP = ?
Gas constant = 0.0821 atm.L/mol.K
Solution:
Number of moles of gas:
Number of moles = mass/molar mass
Number of moles= 14 g/ 14 g/mol
Number of moles = 1 mol
Volume of gas:
PV = nRT
1 atm × V = 1 mol × 0.0821 atm.L/mol.K × 273 K
V = 22.41 atm.L / 1 atm
V = 22.41 L
