Your answer
---------------------
CH4
Number of molecules in one mole of CH4 = 6.022 × 10²² [Avogadro's constant ]
Given number of molecules = 3.6 × 10²⁴
So,
------
Number of moles of CH4 i=
[tex] \frac{3.6 \times 10 {}^{24} }{6.022 \times 10 {}^{23} } \\ \\ = 0.0143 \: moles \: (approximately)[/tex]
