How many atoms are in 9.008 mol of Carbon? 0.7500 atoms 1.332 atoms 5.423 x 10^24 atoms 1.496 x 10^ -23 atoms
Zanzabum

 The number  of atoms that are  in 9.008   moles of carbon is

5.423 x 10^24 atoms


<u><em>calculation</em></u>

The  number of atoms is calculated using the Avogadro's   constant

That is   According to  Avogadro's   1  moles  = 6.02 x 10^23  atoms

                                                         9.008  moles= ? atoms

by cross multiplication

= [(9.008  moles x 6.02 x 10^23 atoms)  / 1  mole] = 5.423 x10^24 atoms

a little kitten jumps from a tree and hits the ground 2.6 seconds later.with this information calculate the cat's velocity right
Harlamova29_29 [7]
The initial velocity is equal zero 
and the cat falls freely so the acceleration equal 9.81 m/s^2 
V = Vo + g * t 
V = 0 + (9.81 * 2.6) 
V = 25.5 m/s
