Question

total number of protons in 1.1 g of co2 is​

Answer 1

Answer:

make me as a Brainliest

Explanation:

Each carbon atom contains 6 electrons whereas each oxygen atom contains 8 electrons (equal to the atomic number of the element). Therefore, a molecule of CO2 contains 6+2(8)=6+16=22.

Answer 2

Number of protons in 1.1 g of CO₂ = 3.3121 × 10²³ protons

• To find Number of protons in 1.1 g of CO₂ we need to know number of protons in one mole of CO₂
• Here, Number of protons 1 carbon is 6 and number of protons in 2 oxygen is 16 then total number of protons in one unit of CO₂ is 22          
• Now find number of mole in 1.1 g of CO₂

• The atomic mass of CO₂ is 44 g/mole

Calculations:-

Number of moles = Given mass ÷ atomic mass (N$_{A}$)

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

Number of mole in 1.1g CO₂ = $(\frac{1.1}{44} )6.022 . 10^{23}$  = 0.15055×10²³

Number of moles in 1.1g of CO₂ is 0.15055×10²³ moles

⇒ 1 moles of CO₂ contains 22 protons

Number of protons in 0.15055×10²³ moles = 0.15055×10²³ × 22  

                                                                       =3.3121×10²³

Number of protons in 1.1 g of CO₂ = 3.3121 × 10²³ protons
