Question

What mass of so² will contain 1.2NA of oxygen atom?

Answer 1

Answer:

1 mole of any substance has 6.023 × 10∧23 molecules or atoms.

Molar mass of SO2 = 64

molar mass of CO2 = 44

Find the moles of 4.4 g of CO2:

moles = mass/molar mass

 

         = 4.4/44

         = 0.1 moles

0.1 moles of CO2 has the same number of molecules 0.1 moles of SO2:

Find the mass of SO2 with 0.1 moles

mass = moles × molar mass

 

          =  0.1 × 64

         = 6.4 grams
