Answer:

90.37 g

Explanation:

From Avogadro Number,

1 mole of every substance contains a particle number of 6.02×10²³

From the question,

1 mole of CH₄ contains 6.02×10²³ molecules.

But,

1 mole of CH₄ has a mass of 16 g

Therefore,

16 g of CH₄ contains 6.02×10²³ molecules

Then,

Y g will contain 3.4×10²⁴ molecules

Solve for Y

Y = (16× 3.4×10²⁴)/(6.02×10²³)

Y = 90.37 g
