If 1.2 L of solution contains 0.97 mol
then let 1 L of solution contain x mol
⇒ (1.2 L) x = (0.97 mol) (1 L)
x = (0.97 mol · L) ÷ (1.2 L)
x = 0.8083 mol
Thus the molarity of the Barium Chloride solution is 0.808 mol / L OR 0.808 mol/dm³.
Answer:
B: it allow quick conversation to others
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.
Mitosis is where the cell divides its previously-copied DNA and cytoplasm to make two new, identical daughter cells.
