Answer:
How many grams of potassium chloride, KCl, must be dissolved in 500.0 mL of solution to produce a 1.5 M solution? Answer: g 4. What is the molarity of a solution in which 84.0 grams of sodium chloride, NaCl, is dissolved in 1.25 liters of solution? Answer: M 5.
Explanation:
That would be A.
2.5*2*10^(10-7)=5*10^3
Pressure can affect the boiling pressure of a substance
as when pressure increases the particles are closer together and so require more energy to boil therefore increasing the substances boiling point
