Which is the correct mole ratio for aluminum chloride to chlorine in the chemical reaction alcl3 br2 ? albr3 cl2?

Answer : The mole ratio for aluminium chloride to chlorine is, 2 : 3

Explanation :

The given unbalanced chemical reaction is :

First we have to balance the chemical reaction.

In order to balance the chemical reaction, the coefficient 2 is put before and the coefficient 3 is put before .

The given balanced chemical reaction will be :

By the stoichiometry we can say that, 2 moles of react with 3 moles of to give 2 moles of and 3 moles of as a product.

That means,

The mole ratio between the are respectively.

Thus, the mole ratio for aluminium chloride to chlorine is, 2 : 3

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
