Answer 1

We assume you are converting between moles Na2CO3 and gram. You can view more details on each measurement unit: molecular weight of Na2CO3 or grams This compound is also known as Sodium Carbonate. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Na2CO3, or 105.98844 grams

Answer 2

no. of moles*avogadro's no

na=0.50*2*6.022*10^(23)=6.022*10^(23)

c=0.5*6.022*10^(23)=3.011*10^(23)

o=0.5*3*6.022*10^(23)=9.033*10^(23)
