At STP, 22.4 L is the total volume occupied by a 2.00-gram sample of [tex]H_2[/tex](g).
What is STP?
Standard temperature and pressure, abbreviated STP, refers to nominal conditions in the atmosphere at sea level.
Molar mass ([tex]H_2[/tex] ) = 2 g/mol
Solute = 2.00 g
Number of moles:
[tex]Moles = \frac{mass}{molar \;mass}[/tex]
[tex]Moles = \frac{2}{2}[/tex]
Moles =1
Moles= 1 moles of [tex]H_2[/tex]
1 mol [tex]H_2[/tex] ------------ 22.4 L STP
Hence, at STP, 22.4 L is the total volume occupied by a 2.00-gram sample of [tex]H_2[/tex](g)
