is converted into mechanical energy. The mechanical energy
moves the car .
if you know that I am right please mark it as brainliest
Answer
is: 325.5 mL of the stock solution.
c₁(AgNO₃)
= 0.675 M.
<span>
V</span>₂(AgNO₃) = 0.879 L.<span>
c</span>₂(AgNO₃) = 0.250 M.<span>
V</span>₁(AgNO₃) = ?<span>
c</span>₁ -
original concentration of the solution, before it gets diluted.<span>
c</span>₂
- final concentration of the solution, after dilution.<span>
V</span>₁
- <span>volume to
be diluted.
V</span>₂ - <span>final volume after
dilution.
c</span>₁ · V₁ = c₂
· V₂.<span>
V</span>₁(AgNO₃) = c₂ · V₂ ÷ c₁.<span>
V</span>₁(AgNO₃) = 0.250 M · 0.879 L ÷ 0.675 M.<span>
V</span>₁(AgNO₃) = 0.325 L · 1000 mL = 325 mL.
