A spherical storage tank contains high pressure methane $($molecular mass $16\mathrm{.}04$ g$/$mol$).$ The tank is constructed out of a material with a design tensile strength of $137$ MPa and a wall thickness of $2$ cm$,$ and has a diameter of $24$ meters. The entire container is maintained at $-1$ degrees Celsius. How many metric tons of methane can be safely stored in this tank? $($Recall that a metric ton is equal to $1000$ kg or $1$ Mg and assume ideal gas$).$
