Ophelis was painted by a British artist named, Sir John Everett. It was first completed in 1852 starting from 1851.
Warm air is transferred from the surface to high elevations near the eye, further accelerating winds and circulation. Composed of rows of cumulonimbus clouds--big thunderstorm. They are usually the first part of the cyclone to arrive on land. Yw
The volume of gas that exerts a pressure of 457 mmhg if exerted a pressure of 2.50 atm when its volume was 25.0ml is calculated as follows
by use of Bolyes law formula that is P1V1=P2V2
P1= 457mmhg
V1=?
P1 = 2.50 atm = 2.50 x760 = 1900mmhg
V2= 25,0 ml
V1 from the formula above = P2V2/P1
= 1900mm hg x25 ml/ 457 mm hg = 104 ml

Answer: 3.01 x 10^24 atoms
Explanation:
Based on Avogadro's law:
1 mole of any substance has 6.02 x 10^23 atoms
So, 1 mole of SI = 6.02 x 10^23 atoms
5.0 moles = Z atoms
To get the value of Z, cross multiply:
(Z atoms x 1 mole) = (6.02 x 10^23 atoms x 5.0 moles)
Z atoms•1 mole = 30.1 x 10^23 atoms•moles
Divide both sides by 1 mole
Z atoms•1 mole / 1 mole = 30.1 x 10^23 atoms•moles / 1 mole
Z = 30.1 x 10^23 atoms
[Place Z in standard form
So, Z = 3.01 x 10^24 atoms]
Thus, there are 3.01 x 10^24 atoms in 5.0 moles in SI
