Answer:

#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#
