In a 50 g living tissue, the amount of water would be

Options

A. 15 - 25 g
B. 25 - 30 g
C. 35 - 45 g
D. 70 - 90 g.

Answer

To determine the amount of water in a 50 g living tissue, we can follow these steps:

### Step 1: Understand the water content in living tissues
Living tissues contain a significant amount of water, typically around 70-80% of their total mass.

### Step 2: Calculate the water content in 50 g of living tissue
To find the amount of water in 50 g of living tissue, we can use the average percentage of water content. For this calculation, we will use the average of 70% for simplicity.

\[ \text{Water content} = \text{Total mass of tissue} \times \text{Percentage of water} \]
\[ \text{Water content} = 50 \, \text{g} \times 0.70 = 35 \, \text{g} \]

### Step 3: Determine the range of water content
Since the water content can vary, we can consider a range. If we take 65% to 75% as the range for the water content:

- **Lower limit (65%)**:
\[ \text{Water content} = 50 \, \text{g} \times 0.65 = 32.5 \, \text{g} \]

- **Upper limit (75%)**:
\[ \text{Water content} = 50 \, \text{g} \times 0.75 = 37.5 \, \text{g} \]

### Step 4: Conclude the amount of water in living tissue
From the calculations, we find that the water content in 50 g of living tissue is approximately between 32.5 g and 37.5 g. This aligns with the option of 35 to 45 grams.

### Final Answer
The amount of water in a 50 g living tissue would be **35 to 45 grams**.
