Answer 2

Calculation of Mass of Lactic Acid Solution Formed

To calculate the mass of the lactic acid solution formed, we need to consider the initial mass of cellulose and the percentage of cellulose that undergoes hydrolysis.

Given: - Mass of cellulose: 1000 grams - Percentage of cellulose that undergoes hydrolysis: 50%

To find the mass of the lactic acid solution formed, we need to calculate the mass of cellulose that undergoes hydrolysis and then determine the mass of lactic acid formed.

Step 1: Calculate the mass of cellulose that undergoes hydrolysis The mass of cellulose that undergoes hydrolysis can be calculated by multiplying the mass of cellulose by the percentage of cellulose that undergoes hydrolysis.

Mass of cellulose that undergoes hydrolysis = Mass of cellulose * Percentage of cellulose that undergoes hydrolysis

Mass of cellulose that undergoes hydrolysis = 1000 grams * 50% = 500 grams

Step 2: Calculate the mass of lactic acid formed To determine the mass of lactic acid formed, we need to consider the reaction of glucose formed from the hydrolysis of cellulose undergoing lactic acid fermentation.

Given that the mass fraction of lactic acid in the solution is 24%, we can calculate the mass of lactic acid formed by multiplying the mass of cellulose that undergoes hydrolysis by the mass fraction of lactic acid.

Mass of lactic acid formed = Mass of cellulose that undergoes hydrolysis * Mass fraction of lactic acid

Mass of lactic acid formed = 500 grams * 24% = 120 grams

Therefore, the mass of the lactic acid solution formed is 120 grams.

Please note that the information provided is based on the given data and calculations.
