What is the volume of consumed during acid hydrolysed of 1.398 kg of sucrose? (Given: molar masses of sucrose water =18, density of water = 1g/`cm^(3)`)A. `0.072 dm^(3)`B. `0.720 dm^(3)`C. `0.18 dm^(3)`D. `0.018 dm^(3)` |

Answer» Correct Answer - A Hydrolysis of sucrose is as `C_(12)H_(22)O_(11) + H_(2)O to C_(6)H_(12)O_(6) + C_(6)H_(12)O_(6)` `therefore w = (1368 g xx 18 g)/(343) = 72 g = 72 cm^(3)` `(therefore d = 1g cmp^(-3))` But `1 dm^(3) = 10^(-3) cm^(3)` `therefore` Volume of `H_(2)O = 72 xx 10^(-3) dm^(-3)` `=0.072 dm^(3)` |
