Answer:the answer is C
Explanation:
I got it right on my test
Molarity of solution = 0.08 M
<h3>Further explanation </h3>
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
Where
M = Molarity
n = number of moles of solute
V = Volume of solution
Volume of solution = 100 ml + 150 ml = 250 ml
Answer:
P₂ = 5000 KPa
Explanation:
Given data:
Initial volume = 2.00 L
Initial pressure = 50.0 KPa
Final volume = 20.0 mL (20/1000=0.02 L)
Final pressure = ?
Solution:
The given problem will be solved through the Boly'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
50.0 KPa × 2.00L = P₂ × 0.02 L
P₂ = 100 KPa. L/0.02 L
P₂ = 5000 KPa
