What is the empirical formula for<br> P2S3 ?
tatiyna

Answer : The empirical formula is P_2S_3.

Explanation :

Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.

Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.

The given molecular formula is P_2S_3.

For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.

In the given formula, the valence is 1.

So, the empirical formula is P_2S_3.

Solve the following problems on ideal gas equation. Practice makes perfect.
photoshop1234 [79]

Answer:

0.012mol

Explanation:

1.

Given parameters:

Pressure in the balloon  = 1.25atm

Volume of the balloon  = 2.5L

Unknown:

Number of moles  = ?

Solution:

We are going to used the combined gas law to solve this problem.

  PV = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas constant  = 0.082atmdm³mol⁻¹K⁻¹

 Insert the parameters and solve;

    1.25 x 2.5  = n x 0.082 x 285

       n  = 0.13mol

The number of moles is 0.13mol

2.

Given parameters:

Pressure  = 16torr;

   to atm is ;

                 760torr  = 1atm

                  16torr = \frac{16}{760}   = 0.02atm

Volume = 12L

Temperature  = 253K

Using the ideal gas law;

        PV  = nRT

       0.02x12  = n x 0.082 x 253

            n = 0.012mol
