Calculate the equilibrium pressure (in Pascal) for the conversion of graphite to diamong at `25^(@)C.` The densities of graphite and diamond may be takes to be `2.20` and `3.40` g//cc respectively independent of pressure. (Express your answer in scientific notation x `xx10gamma` and write the value of y.)
[Given : `DeltaG_(298)^(@)` `(C_("graphite") rarr C _("diamond"))=2900J//mol]`
