Answer:

9.39 × 10²² molecules

Explanation:

We can find the moles of gases (n) using the ideal gas equation.

P . V = n . R . T

where,

P is the pressure (standard pressure = 1 atm)

V is the volume

R is the ideal gas constant

T is the absolute temperature (standard temperature = 273.15 K)

n=\frac{P.V}{R.T} =\frac{1atm.3.50L}{(0.08206atm.L/mol.K).273.15K} =0.156mol

There are 6.02 × 10²³ molecules in 1 mol (Avogadro's number). Then,

0.156mol.\frac{6.02\times10^{23}molecules}{mol} =9.39\times10^{22}molecules
