Answer:
One mole of Carbon contains 6.022x10^23 atoms.
3.75 moles of carbon contains ( 6.022x10^23 ) x ( 3.75 ) = <u>2.26x10^24 Atoms</u>.
One mole of every element or compound is equal to 6.022x10^23 number of Atoms or Molecules and this number of atoms is known as Avogadro's Number.
23.0 g/ (4.50 g/ mL) gives 5.11 mL as the volume.
Answer: Option (B) is the correct answer.
Explanation:
According to Le Chatelier's principle, any disturbance causes in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
For example, 
When we increase the temperature then the reaction will shift in a direction where there will be decrease in temperature.
This, means that the reaction will shift in the backward direction.
Thus, we can conclude that if the reaction is at equilibrium and the temperature increases, the equilibrium will shift so that there is more nitrogen dioxide.
64.066 g/mol is the weight
1L=1000 mL,L GOES BOTTOM AND mL GOES TOP,ANSWER SHOULD BE 42700.
