Question

Целюлозу масою 324 грам гідролізували і добутий продукт спиртовому бродінню.добули етанол масою 170 грам.обчисліть вихід етанолу

Answer 1

C6H10O5 + H2O = C6H12O6
C6H12O6 = 2CO2 + 2C2H5OH

n целюлоза = 342/162 = 2моль
m етанол = 2*92 = 184грам
w етанол = 170/184*100% = 92,4%

Answer 2

Calculation of Ethanol Yield

To calculate the yield of ethanol, we need to determine the percentage of the starting material (cellulose) that was converted to ethanol.

Given: - Mass of cellulose = 324 grams - Mass of ethanol obtained = 170 grams

To calculate the yield of ethanol, we can use the following formula:

Yield (%) = (Mass of ethanol obtained / Mass of cellulose) * 100

Substituting the given values into the formula:

Yield (%) = (170 grams / 324 grams) * 100

Calculating the yield:

Yield (%) = 0.524 * 100

Yield (%) = 52.4%

Therefore, the yield of ethanol is 52.4%.
