Answer:- 1.62 moles
Solution:- At constant temperature and pressure, volume is directly proportional to the moles of the gas.

from given data,
= 5.17 L,
= 1.05 moles
= 8.00 L,
= ?
Let's plug in the values in the formula:

On cross multiply:

= 1.62 moles
So, now the toy contains 1.62 moles of the air.
Answer: is C
Explanation:
Both the atomic mass and the atomic number increase from left to right
Number of moles of the gas, Temperature and the volume of the gas.
Answer:
Molarity = 0.5 M
Osmolarity = 0.5 x 2 = 1 Osmpl.
Molecules of Cl2 = 6.02 x
/ 4= 1.505 x
no. of molecules
Explanation:
If we add half mole in 1L volume than molarity will obviously be 0.5 M.
The osmolarity is molarity multiplies by number of dissociates of solute that for CaCl2 are 2. So, 2 x 0.5 = 1
Half will be molecules of Ca and half will be of Cl2 for 0.5M.
