Question

The volume of a gas at 0 degree celsius and 700mm pressure is 760cc. The no.Of molecules present in this volume is

Answer 1

Explanation:

From ideal gas equation

PV = nRT

n = PV / (RT)

= 700/760 atm × 760 × 10⁻³ L / (0.0821 L atm / (mol K) × 273 K)

= 0.03 mol

= 0.03 × 6.022 × 10²³ molecules

= 1.80 × 10²² molecules

∴ 1.80 × 10²² molecules are present in the given volume.

Answer 2

Answer:

Here is solution mate❤️

Explanation:

n = PV / (RT)

n = PV / (RT)= 700/760 atm × 760 × 10⁻³ L / (0.0821 L

atm / (mol K) × 273 K)

= )0.03 molecules

=) 0.03 × 6.022 × 10²³ molecules

0.03 × 6.022 × 10²³ molecules= )1.80 × 10²² molecules

So, there will be 1.80 × 10²² molecules are present in given volume.Mark as Brainliest
