Answer 1

A 22.4-L sample of which of the following substances, at STP, would contain 6.02 x 1023 representative particles should be nitrogen. The answer is C. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Answer 2

Answer The correct answer is option(C).

Explanation;

At STP, volume occupied by the ideal gas = 22.4 l

At STP the value of Temperature is 273 K

At STP the value of value of pressure is 1 atm.

According to ideal gas equation;

PV=nRT

$n=\frac{PV}{RT}=\frac{1atm\times 22.4 L}{0.0820 atm L\ mol K\times 273 K}= 1 mol$

1 mole gas will occupy 22.4 l of volume at STP.

From the given options the correct option is option(C) that is nitrogen. This because Nitrogen is exist in gaseous state at STP where as carbon, cesium iodide and silver are solid at STP.
