How many moles of CCl4 are in 3.55L
marishachu [46]

Answer: 0.16 moles

Explanation: According to Avogadro's law, 1 mole of every gas at STP occupies a volume of 22.4 Liters.

Given: Volume occupied = 3.55 L

From Avogadro's law,

22.4 L of CCl_4 corresponds to= 1 mole

3.55 L of CCl_4 correspond to=\frac{1}{22.4}\times 3.55=0.16moles

What is the mole fraction of cation in 1M of aluminium sulphate​
Svetllana [295]

The mole fraction of cation (Al)=0.4

<h3>Further explanation</h3>

Given

1 M of Aluminium sulphate​

Required

The mole fraction of cation

Solution

Ionization of the Aluminum sulfate solution( assume 1 L solution ) :

mol Al₂(SO₄)₃ = M x V = 1 M x 1 L = 1 mol

Al₂(SO₄)₃⇒2Al³⁺ + 3SO₄²⁻

1 mol          2 mol   3 mol

From this equation, total mol in solution = 2+3 = 5 moles

Mol fraction Al(as a cation) :

= 2/5=0.4

A rocket launching in the Ukraine accelerates upwards from rest to a speed of 12 km/s in 8
Leni [432]

Answer: 1.5 km/s²

Explanation:

Given that,

Initial speed Vi = 0 km/s

Final speed Vf = 12km/s

Acceleration A = ?

Time taken T = 8 seconds

Recall that acceleration is the rate of change of velocity per unit time

i.e acceleration = (Vf - Vi)/T

A = (12km/s - 0km/s) / 8 seconds

A = 12km/s / 8 seconds

A = 1.5 km/s²

Thus, the acceleration of the rocket is 1.5 km/s²
