How much of zno should be added 3400g 0f 10% to produce 15%of zno?

Sagot :

Solution:

To find the amount of ZNO needed to produce 15% of ZNO from a 10% solution, we can use the formula for mixing solutions:

  • C1V1 = C2V2

Where:

  • C1 = initial concentration (10% or 0.1)
  • V1 = initial volume (3400g)
  • C2 = final concentration (15% or 0.15)
  • V2 = final volume (unknown)

We need to solve for V2. Rearranging the formula, we get:

  • V2 = (C1 * V1) / C2

Substituting the given values:

  • V2 = (0.1 * 3400g) / 0.15
  • V2 = 233.33g

Therefore, 233.33g of ZNO should be added to produce 15% of ZNO from a 10% solution.
