Question

calculate the number of GMM and number of molecules in 44g of CO2​

Answer 1

Answer:

Gram molecular weight of CO2=12+2×16=44g.

now, 44g of CO 2 contains 6.023×10^23 molecules

since 11g of CO2 contains =6.023×10^23×11/44 =1.51×10^23 molecules.

Explanation:

According to avogadro's law,1 mole of every substance contains avogadro's number 6.023×10^23 of particles .

To calculate the moles ,we use the equation :

Number of moles = Given mass/Molar mass

Given mass of CO2 =44g

Molar mass of CO2=12+32=44g/mol

Number of moles =44g/44g/mol =1 mole

Now 1 mole of CO2 molecule contains =6.023×10^23 of molecules
