If five moles of a gas at a pressure of 5.4 kpa have a volume of 120 liters, what is the temperature?

ra1l [238]

<h3>The temperature is 15.58 kelvin </h3>

<em><u>Solution:</u></em>

<em><u>Ideal gas equation is given as:</u></em>

$PV = nRt$

Where,

P = pressure

V = volume

n = amount of substance

R = ideal gas constant

T = temperature

From given,

V = 120 liters

n = 5 moles

$R = 8.314\ \frac{Lkpa}{mol\ K}$

P = 5.4 kPa

T = ?

Therefore,

$5.4 \times 120 = 5 \times 8.314 \times T\\\\648 = 41.57 \times T\\\\T = 15.58\ kelvin$

Thus the temperature is 15.58 kelvin

Mass of 2×10^21 number of atoms of an element is 0.4g. What is the mass of 0.5 mole of the element?

alexandr402 [8]

Answer:

66.7 g

Explanation:

Number of atoms = 2×10²¹

Mass of 2×10²¹ atoms = 0.4 g

Mass of 0.5 moles of that element = ?

Solution:

1 mole contain 6.022×10²³ atoms

2×10²¹ atoms × 1 mol / 6.022×10²³ atoms

0.33×10⁻² mol

0.003 mol

0.003 mole have mass of 0.4 g

0.5 mol have mass 0.5/0.003×0.4 g = 66.7 g
