Question

On'ginal amount it solute in
[
begin{aligned}
800 mathrm{gm} &=frac{40}{100} times 800
&=320 mathrm{gm}
end{aligned}
]
Affer 100 grn preapituted ( 1 quad 320-100 ) remained in toogm ( =220 mathrm{gm} )
" composition of remaining solution ( =frac{220}{700} times 100 )
[
=31.4 %
]

# 81. 800 g of a 40% solution by weight was cooled. 100 g of solute precipitated. The percentage composition of remaining solution is: (a) 31.4% (b) 57.6% (c) 45.8% (d) 41.4%
