Answer:
2 atm
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 16.0 L
Initial pressure (P₁) = 0.5 atm
Final volume (₂) = 4 L
Final pressure (P₂) =?
The final pressure of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
0.5 × 16 = P₂ × 4
8 = P₂ × 4
Divide both side by 4
P₂ = 8 / 4
P₂ = 2 atm
Thus, the final pressure of the gas is 2 atm
Answer:
White spirits (used in lighter fluid), turpentine and Kerosene can cope with fat/oil stains, tar/asphalt and some adhesives. Many pre-wash spot treatments contain solvents. Mild Acids - such as white vinegar, cream of tartar or lemon juice help remove rust and some food stains.

Answer:
Mass = 0.32 g
Explanation:
Given data:
Mass of CH₄ = ?
Volume of CH₄ = 500 mL (500 mL× 1L/1000 mL= 0.5 L)
Temperature = 273 K
Pressure = 1 atm
Solution:
Volume of CH₄:
500 mL (500 mL× 1L/1000 mL= 0.5 L)
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
By putting values,
1 atm× 0.5 L = n×0.0821 atm.L/ mol.K × 273 K
0.5 atm.L = n×22.4 atm.L/ mol
n = 0.5 atm.L / 22.4 atm.L/ mol
n = 0.02 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.02 mol × 16 g/mol
Mass = 0.32 g
