<h3>The temperature is 15.58 kelvin </h3>
<em><u>Solution:</u></em>
<em><u>Ideal gas equation is given as:</u></em>
Where,
P = pressure
V = volume
n = amount of substance
R = ideal gas constant
T = temperature
From given,
V = 120 liters
n = 5 moles
P = 5.4 kPa
T = ?
Therefore,
Thus the temperature is 15.58 kelvin
Answer:
3.2043 x 10²³
Explanation:
No. of Mole of lead (Pb) = 0.532 mol
No. of atoms of lead = ?
Solution:
Formula Used to calculate
no. of moles = numbers of particles (ions, molecules, atoms) /Avogadro's number
Avogadro's no. = 6.023 x10²³
So,
The formula could be written as
no. of atoms of lead Pb = no. of moles x 6.023 x10²³
Put the values in above formula
no. of atoms of lead Pb = 0.532 mol x 6.023 x10²³
no. of atoms of lead Pb = 3.2043 x 10²³
so 3.2043 x 10²³ atoms of lead are contained in 0.532 mole.
The answer is C multiple alleles
Atom can never be divided into smaller particles is the answer was disproved
