$154 ml$

Find the density of the solution by the formula:
$sp. gravity=(rho " solution")/(rho " water at " 4^oC)$
Rearrange the formula;
$rho " solution"=(sp. gravity)(rho " water at " 4^oC)$
where:
$rho " water at " 4^oC=1 "g/ml"$
Plug in values to find density of solution to the formula in step 2;
$rho " solution"=(1.2)(1 "g/ml")$
$rho " solution"=1.2"g/ml")$
To find the volume:
$V=m/(rho)$ , plug in values
$V=(185cancelg)/(1.2cancel(g)/"ml"$
The $V=154 ml$
