Explanation:
Step 1: Given data
Moles of barium chloride (solute): 4.4 moles
Volume of solution: 1.5 liters
Step 2: Calculate the molarity of barium chloride in the solution
The molarity is a way to quantitatively express the concentration of a solute in a solution. The molarity is equal to the moles of solute divided by the volume, in liters, of solution.
Answer:
200 Joules is the explosive energy in the inside the balloon. And that is 1 lb of TNT.
Explanation:
Volume of the balloon = V = 1 L =
Pressure inside the balloon ,P= 200,000 Pa =
Explosive energy in the inside the balloon be E.
E = Pressure × Volume
1 lb of TNT =
200 Joules = 1 lb of TNT
= 1 lb of TNT
