Question

what will be the volume of 1 gram atom Helium at STP in litres​

Answer 1

Answer:

Before determining the volume of any chemical substance u have make sure that whether it is a gas or not at a particular temp and pressure.. So firstly ur question needs this clarification. ..

Now, if it is a gas… then, u have to check the values of temp and pressure or some general conditions like STP or NTP. So this clarification is again needed..

If the temp and pressure do not resembles with that of STP or NTP then u have to calculate the volume of the gas using Ideal Gas Equation… PV=nRT where, symbols have their usual meanings..

Now, if u r talking about STP or NTP then it goes like this ..

Explanation:

Thus , 4g of He and 22.4L of Helium represents the same amount i.e., 1 mole of Helium..

So, if 4g contains 22.4L of He then , 1g will have the volume of 5.6L.

Hope it makes ur concepts clearer..
