Find the molarity of a solution in which 0.99 mol of NaCl are dissolved in 2.5 L of solution.

0.369M

Explanation:

☆ Volume has to be in litres

Molarity of solution

= 0.99 ÷2.5

= 0.369 M

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.
