Achemistry student needs 65.0g of acetone for an experiment. she has available 250.g of a 12.5% w/w solution of acetone in chloroform. calculate the mass of solution the student should use. if there's not enough solution, press the no solution button. round your answer to 3 significant digits.

No solution.

Explanation:

12.5% w/w  means 12.5 grams of solute in 100 g of solution.

In 100 g of solution we have 12.5 g of solute

250 g of solution have ___ (250 . 12.5)/100 = 31.25 g

250 grams of solution of acetone in chloroform, has 31.25 grams of acetone.

One solution is not enough to the student who needs 65 g.

She would need, two more bottles of 250 grams of solution.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
