Answer:
use renewable energy hshehhdbdbdbd
Explanation:
I makes sense to pick option 2
Based on the question, it is evident that the question is based on Boyle's Law which we will use to find the answer necessary.
Now, Boyle's Equation: P₁V₁ = P₂V₂
V₂ = P₁V₁ ÷ P₂
∴ V₂ = (12.5L × 42.0 cm · Hg) ÷ 75 cm · Hg
⇒ V₂ = 7 L
Thus, the <span>volume when the pressure has increased to 75.0 cm Hg is 7 Litres.</span>
Answer: 0.02 moles
Explanation: Using ideal gas equation:
P = pressure = standard pressure= 1 atm
V = volume = 0.500L
n = no of moles = ?
R = gas constant =0.0821 Latm\molK
T= temperature = 
= (15+273)K= 288K
