A solution with a molarity of 7.65 mol/L and a volume of solution of 0.690 L, contains 5.28 moles of solute.
<h3>What is molarity?</h3>
Molarity is the number of moles of solute per liter of solution.
A solution has a molarity (M) of 7.65 mol/L and a volume (V) of 0.690 L. We can calculate the number of moles of solute (n) using the following expression.
M = n / V
n = M × V = 7.65 mol/L × 0.690 L = 5.28 mol
A solution with a molarity of 7.65 mol/L and a volume of solution of 0.690 L, contains 5.28 moles of solute.

Explanation:
That would be the answer to this
Explanation:
Expression for the
speed is as follows.

where,
= root mean square speed
k = Boltzmann constant
T = temperature
M = molecular mass
As the molecular weight of oxygen is 0.031 kg/mol and R = 8.314 J/mol K. Hence, we will calculate the value of
as follows.

= 
= 498.5 m/s
Hence,
for oxygen atom is 498.5 m/s.
For nitrogen atom, the molecular weight is 0.028 kg/mol. Hence, we will calculate its
speed as follows.

= 
= 524.5 m/s
Therefore,
speed for nitrogen is 524.5 m/s.
