S, WE amilies a 100 ml gradu Density of an Object by Displacement of Water Earlier today / marwed the density of a metal ball by displacement of water using a 100 ml cylinder and centrame balance. First, obrained the mass of the ball. Next, I added water to a graduated onder and measured the initial volume of water. Then, I gently dropped the ball into water and measured the new wolne of water. Below is the data from my...
1. 50 mL of water at 51.9°C were mixed with 50 mL of water at 23.2°C in a calorimeter also at 23.2°C. The final temperature was 33.1°C. Assuming that neither the density of water nor its specific heat capacity change with temperature, calculate the total heat capacity of the calorimeter. (density of water = 1.00 g mlº', specific heat capacity=4.18 J g?K=) 2. When 5.00 g of NaOH(s) are added to 100 g of water (using the same calorimeter as...
