Where subscript 1 refers to the initial concentration and volume, while 2 refers to the final C and V. Meaning that in this case:
We <u>input the data</u>:
- 5.0 M * V₁ = 0.25 M * 100 mL
And <u>solve for V₁</u>:
C or d because ik it’s not consolidated
The chemical formula for potassium phosphate is : KH2PO4
