How many moles are in 62.4g of chlorine gas?

The answer to your question is 0.879 mol of Chlorine

Explanation:

Process

1.- Calculate the molecular mass of Chlorine

   A Cl₂ = 35.5 g x 2

            = 71 g

2.- Calculate the number of moles of Cl₂ in 62.4 g using a rule of three

                                71 g of Chlorine 1 mol

                                 62.4 g                 x

                                 x = (62.4 x 1) / 71

                                 x = 0.879 mol of Chlorine

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

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.
