You will also need to know the pressure to answer this question.

Keep in mind that methane is normally a gas. One mole of a gas occupies 22.4 Liters at STP. Methane has a mol. mass of 16 grams per mole. So at STP there are 16 grams in 22.4 liters. With this you can calculate the density at STP (D=M/V)

Now you have to adjust the temperature to 258K. You will need the pressure, unless it was at 1 atm.

You can calculate the adjusted volume for the same 16 grams and calculate the density.
