Given :

Chlorine's 3p sub level has 5 electrons in it.

To Find :

How many electron(s) more in the 3p sub-level to make it stable.

Solution :

Electronic configuration of Chlorine is :

[Ne] 3s² 3p⁵.

We know, p-orbit is stable with 6 electronic.

Therefore, to stable p-orbit 1 more electron is required in 3p sub-level.

Hence, this is the required solution.

A ringers solution for intravenous fluid replacement contains 155 mEq of Ca2+ per liter of solution. if a patient receives 1850
Nonamiya [84]
Milliequivalent is a unit that made from millimol unit multiplied by the valence of the atoms. Calcium has 2 valence electron so the mEq would be twice as much as the mol. The solution has 155meq/liter and the volume is 1850ml. Then, the amount of calcium in the solution should be:

1850ml * (155mEq/1000ml) / (2mEq/mmol)= 143.375mmol= 0.144 mol

What is the molar mass of ace tic acid
noname [10]

Answer:

Molar mass of acetic acid = 60 g/mol

Explanation:

Molar mass of any compound is the sum of the atomic masses of all the atoms of elements present in it.

Molar mass of acetic acid:

Formula:

CH₃COOH

Atomic mass of carbon = 12 g/mol

Atomic mass of hydrogen = 1 g/mol

Atomic mass of oxygen = 16 g/mol

Molar mass of acetic acid = 12×2 + 1 × 4 + 16× 2

Molar mass of acetic acid = 60 g/mol
