How many moles of hydrogen are there, if there are 4 molecules of hydrogen?

Sagot :

Answer:

Explanation:

In this case, according to the Periodic table

there is 1g of hydrogen per mole. As we know that dihydrogen (H2) has two hydrogen atoms per molecule. So,there will be 2*1g hydrogen per mole=2g dihydrogen per mole.

If there is 2g dihydrogen per mole,and we have 4g,then we know that there is 2 mole dihydrogen in 4g.And for hydrogen there is 4 moles in 4g of hydrogen
