$2.$In an experiment, $2\mathrm{.}00$ X $10^2$ g of silicon dioxide is heated to $96\mathrm{.}7\backslash$deg C and then quickly transferred to $1\mathrm{.}25$X$10^2$ g of water at $15\mathrm{.}2\backslash$deg C$.$ The final temperature comes to $32\mathrm{.}5\backslash$deg C$.$ What is the approximate specific heat capacity of SiO$2?[$cp$($water$)=4\mathrm{.}18$ J$/($g$\backslash$deg C$)]$
