Answer:
Pressure inside soda can = 5.56 atm
Explanation:
Given data:
Initial volume = 1250 mL
Initial pressure = 1.00 atm
Final volume = 225 mL
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.00 atm × 1250m L = P₂ × 225 mL
P₂ = 1250 atm. mL/ 225 mL
P₂ = 5.56 atm

Sulfur, kill me if I'm wrong
Okay what’s the question?
Answer:
7,1x10⁻⁵M = [OH⁻]
Explanation:
pH is the -log of hydronium ion. pOH is -log of hydroxide ion. Knowing pH + pOH = 14:
14 = 9,85 + pOH
pOH = 14 - 9,85
pOH = 4,15
-log [OH⁻] = 4,15
10^-4,15 = [OH⁻]
<em>7,1x10⁻⁵M = [OH⁻]</em>

I hope it helps!
