2.Vitamin C is known to contain 1.20X1024 hydrogen atoms. Calculate the number of moles of hydrogen

The number of moles of Hydrogen : 1.993

Given

1.20 x 10²⁴ hydrogen atoms

Required

The number of moles

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated  :

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

moles of Hydrogen :

what does the table look like

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.
