Step 1: Explaining

$G r a p h i t e space left right double arrow D i a m o n d$

They both are allotropes of carbon so molar mass is 12 gm/mol

For graphite :

$d e n s i t y space open parentheses d close parentheses equals 2.267 space fraction numerator g over denominator c m cubed end fraction triangle S equals 5.740 space fraction numerator J over denominator m o l cross times K end fraction triangle H space equals space 0 space fraction numerator k J over denominator m o l end fraction T equals 298 space K$

For diamond:

$d e n s i t y space open parentheses d close parentheses equals 3.515 space fraction numerator g over denominator c m cubed end fraction triangle S equals space minus 3.363 fraction numerator J over denominator m o l cross times K end fraction triangle H space equals space 1.895 space fraction numerator k J over denominator m o l end fraction T equals 298 space K$
