Answer:
The number of hydrogen atoms is 4.96x10²⁴.
Explanation:
The number of atoms can be found with the following equation:

Where:
N: is the Avogadro's number = 6.022x10²³ atoms/mol
η: is the number of moles of hydrogen
n: is the number of hydrogen atoms
First, we need to find the number of hydrogen moles. The number of moles of CH₄ is:

Where:
m: is the mass of methane = 33 g
M: is the molar mass of methane = 16.04 g/mol

Now, since we have 4 hydrogen atoms in 1 mol of methane, the number of moles of hydrogen is:

Hence, the number of hydrogen atoms is:

Therefore, the number of hydrogen atoms is 4.96x10²⁴.

The balloon would be smaller and not float as well because of the low temperature. The particles in the balloon when in the car will slow down and get closer together because of the low temperature. That caused it to become more dense and smaller in size then before. When in the store, the particulars in the balloon we’re moving faster and more spread apart
