. What is the molarity of a 0.5 liter solution containing 0.7 moles of NaCl?

M = 1.4 M

Explanation:

Hello there!

In this case, according to the given information, it will be possible for us to calculate the required molarity according to its definition:

Whereas the n is mole and has a value of 0.7 mol, V the volume in liters, which is 0.5 L; therefore, the result is:

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.
