How many particles in 32.0 liters of helium

Number of particles : 8.603 x 10²³

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

Number of particles :

the answer would be c

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
