Question

Calculate the no of moles and mo of molecules in 500 mg carbon dioxide

Answer 1

Moles=mass/molar mass

Moles= 500mg/CO2

Moles=500/12+16*2

= 500/44

=11.36 moles

No of molecules= moles*avogardo's number

= 11.36* 6.022*10^23

=6.84*10^24 molecules

U can convert mg into g according to the question asked.
