Answer:
P₂ = 592.7 torr
Explanation:
Given data:
Initial Pressure = 215 torr
Initial volume = 51.0 mL
Final pressure = ?
Final volume = 18.5 mL
Solution:
P₁V₁ = P₂V₂
P₁ = Initial Pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the values in formula.
P₁V₁ = P₂V₂
215 torr × 51.0 mL = P₂ × 18.5 mL
10965 mL. torr = P₂ × 18.5 mL
P₂ = 10965 mL. torr /18.5 mL
P₂ = 592.7 torr
Answer: The glass cup falling
Explanation:
It didnt change chemically, only its physical appearance
Answer:
The original molarity is 1,1030M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
C1= (C2 xV2)/V1
C1= ( 1400 ml x 0,286 M)/363 ml
<em>C1=1,1030 M</em>
