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.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
