Explanation:
Alkanes are the simple hydrocarbons that have only carbon and hydrogen atoms attached to each other through single bonds.
General chemical formula of an alkane is , where n is any integer.
For example, if n = 5 then formula of the alkane will be as follows.
=
=
A suffix "-ane" is added in the name of an alkane. So, an alkane with five carbon atoms will be known as pentane.
Number of molecules in 1 dm³ Oxygen = 2.71 x 10²²
<h3>Further explanation</h3>Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
1 dm³ of oxygen = 1 L Oxygen
- mol Oxygen :
- molecules of Oxygen :
n=mol=0.045
No = 6.02.10²³
