Calculate 25% Water Content: Converting 500g Jam Mixture to Cubic Centimeters

To solve this problem, we'll follow these steps:

• Step 1: Calculate the weight of water.
• Step 2: Convert this weight into volume (cubic centimeters).

Let's work through each step:

Step 1: Calculate the weight of water.
The total weight of the jar's contents is 500 grams. Since 25% of this weight is water, we calculate the weight of water as follows:

$\text{Weight of water} = 25\% \times 500 \text{ grams}$

$\text{Weight of water} = 0.25 \times 500 = 125 \text{ grams}$

Step 2: Convert the weight into volume.
Given that the density of water is 1 gram per cubic centimeter, the volume of water can be directly found as follows:

$\text{Volume of water (in cm}^3\text{)} = \text{Weight of water (in grams)}$

$\text{Volume of water} = 125 \text{ cm}^3$

Therefore, the solution to the problem is 125 cubic centimeters of water.
