Sagot :
The 2.5 x 10²¹ molecules of CH₃OH have 0.00415 moles.
What is the mole concept?
- The Mole concept is used to express the amount of substance conveniently.
- A mole is defined as the amount of substance that contains exactly 6.022 x 10²³ elementary particles of the given substance. Here, elementary particles refer to atoms, molecules, or ions.
- This fixed number 6.022 x 10²³ is known as Avogadro Number and is denoted by [tex]N_A[/tex]
How to calculate the number of moles?
The number of moles is given by
[tex]n=\frac{m}{M}[/tex]
When given mass = molar mass of a substance, then no of moles is equal to 1 which is equivalent to 6.022 x 10²³.
We also know,
1 mole has 6.022 x 10²³ molecules of CH₃OH
According to the mole concept,
6.022 x 10²³ molecules of CH₃OH is equal to 1 mole
2.5 x 10²¹molecules of CH₃OH is equal to [tex]\frac{2.5\times10^2^1}{6.022 \times 10^2^3}[/tex] moles
Thus, 2.5 x 10²¹molecules of CH₃OH are equal to 4.15 x 10⁻³ moles or 0.00415 moles
