Question

the total number of protons and electrons in 1 gram of carbon dioxide

Answer 1

37.0832×10power23...

Answer 2

Number of electrons in 1 g of CO₂ = 30.11 × 10²²

• To find Number of electrons in 1 of CO₂ we need to know number of electrons in one mole of CO₂

• Here, Number of electrons 1 in one unit of CO₂ is 22          

• Now find number of moles in 1 g of CO₂

• The atomic mass of CO₂ is 44 g/mole

Calculations:-

Number of moles = Given mass ÷ atomic mass (N)

                          [ where  N$_{A}$  avogadro's constant = 6.022 × 10²³ ]

Number of moles in 1g of CO₂ = 1/44(6.022 × 10²³) = 1.3686 × 10²²

Number of mole in 1g CO₂ = 1.3686 × 10²²  

⇒ 1 moles of CO₂ contains 22 electrons

Number of electrons in 1.3686 × 10²² moles = 1.3686 × 10²² × 22  

                                                                         = 30.11 × 10²²

Number of electrons in 1 g of CO₂ = 30.11 × 10²²
