Calculation of Water Content in Dried Pears

To calculate the percentage of water content in dried pears, we need to consider the initial water content and the loss of mass during the drying process.

Given that the fresh pears contain 65% water and lose 50% of their mass during drying, we can calculate the water content in the dried pears as follows:

1. Calculate the remaining mass of the dried pears after the drying process: - The dried pears retain 50% of their initial mass after drying, as they lost 50% of their mass during the process.

2. Calculate the water content in the dried pears: - Since the water content in the fresh pears is 65%, the remaining water content in the dried pears can be calculated as 65% of the remaining mass.

Let's perform the calculations:

1. Remaining mass of the dried pears: - The dried pears retain 50% of their initial mass after drying. - Therefore, the remaining mass of the dried pears is 50% of the initial mass.

2. Water content in the dried pears: - The water content in the fresh pears is 65%. - Therefore, the water content in the dried pears is 65% of the remaining mass.
