Question

A solution of salt and water contains 70 grams of water per 140 milliliters of the solution. If 1 mole of water weighs 16 grams, _____ moles of water would be present in 35 milliliters of the solution. [Round off your answer to two decimal places]

Answer 1

Use this:
\[Molarity = \frac{moles}{Volume}\]

Answer 2

Convert the original 70 grams of water to moles. Find the molarity of the solution.
Then, use that molarity to find the amount of moles in 35 mL.

Answer 3

I forgot to say that the volume in the formula is in Liters, not milliliters.
