Calculate the number of hydrogen atoms in 33.0 g CH4

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.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
