# How to calculate the volume of hydrogen which generates from 2g of sodium?

##### 1 Answer

We specify room temperature, atmospheric pressure, and predict a volume of approx

We also ASSUME that the

#### Explanation:

Given this stoichiometry, for every mole of sodium, one half a mole of dihydrogen is evolved.

Moles of

Given the stoichiometry,

Now it is a fact, that at room temperature (

So given the conditions stated and assuming ideality,
