Answer:
Volume required from standard solution = 4675 mL
Explanation:
Given data:
Final volume = 75.0 mL
Final molarity = 130 M
Molarity of standard solution = 2.000 M
Volume required from standard solution = ?
Solution:
We use the formula,
C₁V₁ = C₂V₂
here,
C₁ = Molarity of standard solution
V₁ = Volume required from standard solution
C₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula,
C₁V₁ = C₂V₂
2.000 M × V₁ = 130 M × 75.0 mL
V₁ = 9750 M. mL / 2.000 M
V₁ = 4675 mL
Acceleration i am pretty sure
Answer:
45 mol
Explanation:
First you need to balance the equation:
6K + Cr2O3 = 3K2O + 2Cr
the proportion of the coeficients of potassium and chromium oxide is 6 to 1 so we need to multiply 7.5 by 6 to get 45.
