xxTIMURxx [149]

Answer:

Relative molecular of the compound or infomation like vapour density, volume occupied by a known mass of its vapour at stp, etc

Explanation:

The molecular mass of a compound is twice its vapour density. We can find the molecular formula using the relationship below:

  •    Empirical formula is the simplest formula of a compound. It repeats itself "n" times to become a molecular formula i.e (EF)ₙ = MF...... n is the number of times the empirical formula presents in a mole of the compound.
  • Most times, n is a whole number like 1,2,3,.....

Answer : The volume of gas will be, 113.5 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 60 atm

P_2 = final pressure of gas = 30 atm

V_1 = initial volume of gas = 29 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 115 K

T_2 = final temperature of gas = 225 K

Now put all the given values in the above equation, we get:

\frac{60atm\times 29L}{115K}=\frac{30atm\times V_2}{225K}

V_2=113.5L

Therefore, the volume of gas will be, 113.5 L
