Question

Calculate the number of atoms of oxygen and
carbon in 5 moles of CO2,​

Answer 1

Answer:

compound -5CO2

Explanation:

no. of carbon atoms =5*1=5

no. of oxygen atoms =5*2=10.

Answer 2

• $\sf{3.011\:×\:10^{24}}$

Explanation:

• 1 mole of $\sf{CO_{2}}$ contains 2 moles of oxygen
• 5 moles of $\sf{CO_{2}}$ contain 10 moles of oxygen

❶ Formula,

• Number of atoms of oxygen = Number of moles of oxygen × Avogadro's number

Applying values,

⟼ $\sf{10\:×\:(6.023\:×\:10^{23})}$

⟼ $\sf{6.023\:×\:10^{24}}$ atoms of oxygen

• 1 mole of $\sf{CO_{2}}$ contains 1 mole of carbon
• 5 moles of $\sf{CO_{2}}$ contains 5 moles of carbon.

❷ Formula,

• No. of. atoms of carbon = No. of. moles of carbon × Avogadro's number

Applying values,

⟼ $\sf{5\:×\:(6.023\:×\:10^{23})}$

⟼ $\sf{3\:×\:10^{24}}$ atoms of carbon

• Hence, The no. of. atoms of carbon = $\sf{3\:×\:10^{24}}$
