Question

hello .......‍♀️

QUESTION :

● A gas cylinder can hold 1 kg of hydrogen at room temperature and pressure :

(i) find the number of moles of hydrogen present ........

Now , I have the answer to this question in a book but that answer seems to be wrong ......I guess ‍♀️.....

So can you pls tell me if the answer is correct or not pls pls pls pls

the answer is there in the attachment above , you can see it and tell if that is correct..........and you will get a brainliest mark too !!!!°!!!!!!!!!!!!!!!!​

Answer 1

Answer:

The mass of hydrogen = 1kg×1000g/kg = 1000 g. The molar mass of hydrogen is 2 g/mol. The number of moles of hydrogen present =massmolarmass=10002=500mol. Hence, the number of moles of CO2 = the number of moles of H2 = 500 mol.
