The amount of energy absorbed by the 325g of water is 57,057J. Details about calorimetry can be found below.
<h3>How to calculate energy?</h3>
The energy absorbed by a mass of substance can be calculated using the following formula;
Q = mc∆T
Where;
- Q = quantity of heat absorbed
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
Q = 325g × 4.18 × (92 - 50)
Q = 57,057J
Therefore, the amount of energy absorbed by the 325g of water is 57,057J.

I took the mg and converted it to grams. That gave me .325 grams. I took that and multiplied that by 3628 grams. If I did my math correctly, the answer would be 1179.1. Rounded up, that would be 1179 aspirin tablets.
Hope this helps. :)
B calcium I believe is the answer
Answer:
4.7 × 10⁴ J
Explanation:
Step 1: Given data
- Initial temperature: 25 °C
- Final temperature: 100 °C
- Specific heat capacity of water (c): 4.184 J/g.°C
Step 2: Calculate the temperature change (ΔT)
ΔT = 100 °C - 25 °C = 75 °C
Step 3: Calculate the heat required (Q) to raise the temperature of the water
We will use the following expression.
Q = c × m × ΔT
Q = 4.184 J/g.°C × 150 g × 75 °C = 4.7 × 10⁴ J
