m=0.714g " of " CH_4

Explanation:

At STP, the molar volume is equal to 22.42"L/mol", therefore, to calculate the number of mole of CH_4 that fill a 1.00L flask by:

?mol=1.00cancel(L)xx(1mol)/(22.42cancel(L))=0.0446 mol

Now, to calculate the mass of CH_4 in question:

?g=0.0446cancel(mol)xx(16.01g)/(1cancel(mol))=0.714g " of " CH_4
