At 20°c solubility of sugar is 179.How much gram of sugar is needed to prepare saturated solution with 40gm of water​

Volume is 22,3 ml

Explanation:  I assume solubility is expressed to 100 ml water

You can use proportion :  179 g / 100 ml water =  40 gm/ V

Multiplying the proportion gives 179 g  · V = 100 ml · 40 g | : 179 g

V = 4000  ml / 179 = 22,3 ml

i'm assuming that the correct answer is indeed the first one/ "a"..

im not exactly sure but i think its b!
