If the pOH of vinegar is 9.45, what is its OH
Nadusha1986 [10]

Answer:

[OH⁻] = 3.55×10⁻¹⁰M

Explanation:

Given data:

pOH of vinegar = 9.45

[OH]  = ?

Solution:

Formula:

pOH = -log[OH⁻]

Now we will put the value of pOH.

9.45 = -log[OH⁻]

[OH⁻] = 10∧-pOH

[OH⁻] = 10⁻⁹°⁴⁵

[OH⁻] = 3.55×10⁻¹⁰M

At 25ºC, the average velocity of a hydrogen molecule is 1.92 x 103 m/s. What is the average velocity of a nitrogen molecule at t
notsponge [240]

Answer:

V = 513.36m/s

Explanation:

Temperature (T) = 25°C = (25 + 273.15) = 298.15K

Speed (V) = 1.92*10³m/s

According to kinetic theory of gases, the speed (v) of a molecule is

V= √(3RT / M)

V = speed or velocity

R = ideal gas constant = 0.082J/mol.K

T = temperature of the gas

M = molar mass

Molar mass of hydrogen molecule = 2.0g/mol

Molar mass of Nitrogen molecule = (2×14.0) = 28.0g/mol

Since they're in the same temperature

V1 / V2 = √(M2 / M1)

1.92×10³ / V2 = √(28 / 2)

1.92×10³ / V2 = √(14)

1.92*10³ / V2 = 3.74

1.92*10³ = 3.74V2

V2 = 1920 / 3.74

V2 = 513.36m/s

The velocity of Nitrogen molecule is 513.36m/s
