How many atoms are in 1.4 mol of phosphorus trifluoride (PF3)?

harkovskaia [24]

NA = 6.022*10^23
number of atoms = number of moles * avogadros number
number of atoms = 6.022*10^23 * 1.4 moles * 4 atoms / molecules of PCl3
Number of atoms = 3.37*10^23 atoms.

1) How many moles of gas occupy 58 L at a pressure of 2.2 atmospheres and a temperature

Sergio039 [100]

Here, we need to solve this problem using Ideal gas law ( PV=nRT).

Where –

P = Pressure in atm
V = Volume in L
n = moles
R = Ideal gas law constant
T = Temperature in K

Now, according to the question –

V = 58 L
P = 2.2 atm
T = 313 K
R = 0.0821 atm L/ mol K

Calculation –

$\qquad$ $\pink{\twoheadrightarrow\bf PV = nRT}$

$\qquad$ $\twoheadrightarrow\sf n = \dfrac{PV}{RT}$

$\qquad$ $\twoheadrightarrow\sf n = \dfrac{ 2.2 \: \:\times 58 \: } {0.0821 \times 313}$

$\qquad$ $\twoheadrightarrow\sf n = \dfrac{ 2.2 \times 58}{0.0821 \times 313}$

$\qquad$ $\twoheadrightarrow\sf n =\dfrac{127.6}{25.7}$

$\qquad$ $\pink{\twoheadrightarrow\bf n = 4.9656 \: moles }$
