The required temperature of the sample of gas is 823K.
<h3>What is ideal gas equation?</h3>
Ideal gas equation gives idea about the behavior of gas at different condition & represented as:
PV = nRT, where
- P = pressure = 500 torr = 0.657 atm
- V = volume = 5.01 L
- R = universal gas constant = 0.082 L.atm / K.mol
- T = temperature = ?
- n = moles
Moles will be calculated as:
n = W/M, where
- W = given mass
- M = molar mass
Moles of Neon gas = 1g / 20.1g/mol = 0.049 mole
On putting all these values in the above equation, we get
T = (0.657)(5.01) / (0.049)(0.082) = 822.8 = 823 K
Hence required temperature of the sample is 823 K.

When sodium hydroxide (NaOH) is added to benzoic acid (C
), sodium benzoate and water (
) are formed because benzoic acid is weak acid and NaOH is strong base. The reaction is shown in diagram 1. To the tube of sodium benzoate, if 6 m HCl is added, sodium benzoate salt will react with HCl and produce benzoic acid and sodium chloride, NaCl. The reaction is shown in diagram 2.
