N=V/Vm

n - the number of moles
V - the volume
Vm=22.4 L/mol - the standard molar volume of gas

Answer: {\text {no of moles}}=\frac{\text {Given volume}}{\text {Standard Molar volume}}

Explanation:

According to Avogadro's law, 1 mole of every gas occupies 22.4 L of volume at standard temperature and pressure conditions.

Thus Standard molar volume of substance= 22.4 L

To calculate the moles from mass ,we use the formula:

{\text { no of moles}}=\frac{\text{Given mass}}{\text{Molar mass}}

To calculate the moles from volume ,we use the formula:

Similarly, {\text {no of moles}}=\frac{\text {Given volume}}{\text {Standard Molar volume}}

What amount of sucrose (C12H22O11) should be added to 5.83 mol water to lower the vapor pressure of water at 50 °C to 72.0 torr?
Triss [41]

Answer:

The amount of sucrose that must be added is 1.66 moles

Explanation:

Colligative property of lowering vapor pressure has this formula:

Vapor pressure of pure solvent (P°) - Vapor pressure of solution = P° . Xm

We have both vapor pressure (pure solvent and solution9, so let's determine the ΔP

ΔP = 92.6 Torr - 72 Torr = 20.6 Torr

Let's add the data in the formula

20.6 Torr = 92.6 Torr . Xm

Xm = Mole fraction of solute → (mol of solute/ mol of solute + mol of solvent)

Mol of solvent = 5.83 mol (data from the problem)

Therefore Xm = 20.6 Torr / 92.6 Torr → 0.222

Let's find out the moles of solute (our unknown value)

0.22 = moles of solute / moles of solute + 5.83 moles of solvent

0.222 (moles of solute + 5.83 moles of solvent) = moles of solute

0.222 moles of solute + 1.29 moles of solvent = moles of solute

1.29 moles of solvent = moles of solute - 0.222 moles of solute

1.29 moles = 0.778 moles of solute

1.29 / 0.778 = moles of solute → 1.66 moles

What characteristic bright line spectrum of an elementforced when electrons?
emmasim [6.3K]

The characteristic bright-line spectrum of an element is produced when its electrons return to lower energy levels To be in the ground state all electrons must be in their lowest energy state; all excited atoms must lose energy. The lost energy appears in the form of light. Hope this helped :)
