The volume of the balloon is approximately 2652 liters.
<h3>How to determine the volume occupied by the gas in a balloon </h3>
Let suppose that <em>flammable</em> hydrogen behaves ideally. GIven the molar mass ( ), in kilograms per kilomole, and mass of the gas (
), in kilograms per kilomole, and mass of the gas ( ), in kilograms. The volume occupied by the gas (
), in kilograms. The volume occupied by the gas ( ), in cubic centimeters, is found by the equation of state for <em>ideal</em> gases:

Answer:
=7.89013× 10^47 moles of zinc
Explanation:
1 atom contains 6.023×10^23 moles.
1.31×10^24 atoms of zinc contain6.023×10^24×1.31×10^.24
 
        
             
        
        
        
x = 1.01
Explanation:
Given equation: 
    y = 1.2345x – 0.6789
    y = 0.570
Problem: 
Solving for x
The variables in this equation are y and x
They can take up any value since they are variables. 
   Since we have been given y = 0.570
          y = 1.2345x – 0.6789
To solve for x, we simply substitute for y in the equation; 
      since  y = 0.570
      0.57 = 1.2345x – 0.6789
     add 0.6789 to both sides; 
  0.57 + 0.6789 =  1.2345x – 0.6789 + 0.6789 
   1.2489 =   1.2345x 
Divide both sides by  1.2345
   
 
     x = 1.01

Answer: A hydrogen bonding is interaction between lone pair and hydrogen atom. An Ion-Dipole interaction is the interaction between an ion formed and a dipole. Dipole forms because of the electronegativity difference between two atom participating in the bond formation, and an ion is formed when an atom gains or lose electron. This ion-dipole interaction is strongest interaction.
Therefore, The right choice is (B)
