Question

find out number of molecules in 500 gram of caco 3​

Answer 1

Answer:

30.115 × 10^-23

Explanation:

no. of moles of CACO3 = given mass/molar mass

= 500/100

= 5

no. of moles of CACO3 = no. of molecules/Avogrado Number (NA)

5 = no. of molecules/6.023 × 10^-23

no. of molecules = 30.115 × 10^-23
