Answer:
Number of moles = 2.72 mol
Explanation:
Given data:
Number of moles of H₃PO₄ present = ?
Molarity of solution = 18.1 M
Volume of solution = 150.0 mL (150/1000 = 0.15 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
By putting values,
18.1 M = number of moles / 0.15 L
Number of miles = 18.1 M × 0.15 L
Number of moles = 2.72 mol
Why is a map considered a model?
Answer:
Every map is a representation of reality, thus a model in the broadest sense. Sometimes mapping is distinguished from modelling by stating that mapping is a simple representation of reality, while modelling is trying to cover more complexity in reality.
