Answer:
Zinc is Zn and Magnesium is Mg
Answer:
0.200 M
Explanation:
Step 1: Given data
- Mass of CoCl₂ (m): 2.60 g
- Molar mass of CoCl₂ (M): 130. g/mol
- Volume of solution (V): 100. mL (0.100 L)
Step 2: Calculate the moles (n) of CoCl₂ (solute)
We will use the following expression.
n = m / M
n = 2.60 g / (130. g/mol) = 0.0200 mol
Step 3: Calculate the molar concentration of the solution
Molarity is equal to the moles of solute divided by the liters of solution.
M = n/V
M = 0.0200 mol/0.100 L = 0.200 M
The molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.
<h3>Heating of water molecules</h3>
Temperature is defined as a measure of the average kinetic energy of the molecules of a body. The higher the temperature of a body, the higher the kinetic energy of the molecules of the body.
In both systems, we have water molecules that have the same formula H2O. However, the molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.
