Answer:
1.5 x 10²²atoms
Explanation:
Given parameters:
Mass of Br = 1.98g
Unknown:
Number of atoms
Solution:
A mole of a substance is the amount of substance contained in the avogadro's number of particles.
To solve this problem, we must first find the number of moles present in the given mass of the Br atom:
Number of moles =
=
= 0.025mole.
Now we know that:
1 mole = 6.02 x 10²³
0.025 mole = 0.025 x 6.02 x 10²³ = 1.5 x 10²²atoms
Answer:
The volume is 
Explanation:
From the question we are told that
The number of moles of the gas is 
The volume of the gas is 
The of moles of the gas that leaked is 
Generally from the ideal gas law
Generally at constant pressure and temperature

So 
=> 
=>
=>
