Question

How many particles in 32.0 liters of helium

Answer 1

Number of particles : 8.603 x 10²³

Further explanation

Standard conditions for temperature and pressure are used as a reference in certain calculations or conditions

Assumption⇒ Standard Conditions

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.

1 mol = 6.02 x 10²³ particles (atoms, ions, or molecules)

32.0 liters of Helium

`\tt mol=32:22.4=1.429`

Number of particles :

`\tt 1.429* 6.02* 10^(23)\\\\=8.603* 10^(23)`
