How many liters are there in 3.0 moles of CO2 at STP?

There are 67.2 liters of CO2 at STP

Given

3 mole of CO2

Required

Volume of CO2 at STP

Solution

Standard conditions for temperature and pressure are used as a reference in certain calculations or conditions

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So for 3 moles :

= 3 x 22.4 L

= 67.2 L

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
