Explanation / Answer

a) 5.5 % (m/v) glucose indicates 5.5 g of glucose in 100 ml solution

therefore, amt of glucose in 195 ml = (5.5 * 195)/100 = 10.73 g of glucose

b) 18.5 % (v/v) indicates 18.5 ml of methyl alcohol in 100 ml solution

Therefore, volume of methyl alcohol in 2710 ml solution = (18.5 * 2710)/100 = 501.35 ml
