Three identical flasks contain three different gases at standard temperature and pressure. flask a contains flask b contains o3, and flask c contains n2. which flask contains the largest number of molecules? a) flask a b) flask b c) flask c d) all contain same number of molecules.

All the flasks contain same number of molecules.

Explanation:

STP conditions are called as standard temperature and pressure conditions.

At this condition, 1 mole of a gas occupies a volume of 22.4 L

Also,

The temperature at this condition is taken as 273.15 K  and the pressure at this condition is taken as 1 atm.

According to mole concept:

1 mole of a gas occupies number of molecules

We are given:

Three different flasks having three different gases at STP

So, all the flasks will have same number of molecules that is

Hence, all the flasks contain same number of molecules.

a. they are both space stations
