Answer:
Molarity of solution = 0.9 M
Explanation:
Given data:
Moles of ZnCl₂ = 4.50 mol
Volume of solution = 200 mL
Molarity of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will convert the volume in L.
200 mL×1 L/1000 mL = 0.2L
M = 4.50 mol / 0.2 L
M = 0.9 M

Answer:
122.5 Joule, or 122.5 j
Explanation:
Given,
mass of the object (m) = 5 kg
velocity of the object (v) = 7 m/s
Kinetic energy =
× m × v²
Applying the formula:
Kinetic energy =
× 5 × 7²
⇒
× 5 × 7 × 7
⇒ 
⇒ 122.5 Joule, or 122.5 j
Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
