the fact that u would post ur whole test on here i see if u posting 3 but the whole test Girllllllllll
"Tsunami," the rest are long term and happen over time.
Answer:
Final concentration = 10 M
Explanation:
Given data:
Initial volume = 100 mL
Initial molarity /concentration= 5 M
Final volume = 50 mL
Final molarity/concentration = ?
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume
M₂ = Final molarity
V₂ = Final volume
Now we will put the values.
5 M × 100 mL = M₂ × 50 mL
500 M.mL = M₂ × 50 mL
M₂ = 500 M.mL / 50 mL
M₂ = 10 M
Answer:
3.45 moles Li contains 2.08
