Answer:
The number of atom is 3.67*10^24 atoms
Explanation:
Molar mass of methane CH4 is 16.0g/mol
Using this to divide the mass
24.4g/16.0 = 1.525mol
1 mol CH4 contains 1 mol of Carbon C and 4 mol of hydrogen H, so 1.525mol contains 4(1.525)=6.1 molH
Using avogadro number : (6.1mol)(6.02*10^23)
= 3.67*10^24 atoms
