What volume of a 40.0 % by volume acetone solution can be
made with 20.0 mL of acetone?

50 milliliters of acetone solution

Explanation:

If a solution is 40% by volume of acetone, then we have  40 mL of acetone in a 100 mL solution. So if we have 20 mL of acetone, we get: 100 mL solution 40 mL ( CH3) 2CO⋅

20mL (CH3) 2CO  =50mL solution

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
