Refer to the example about diatomic gases A and B in the text to do problems 20-28.

It was determined that 1 mole of B2 is needed to react with 3 moles of A2.

How many grams in one mole of B2?

__g

28g.

Explanation:

Hello,

In this case, considering the statement, we can infer that the monoatomic atomic mass of B is 14 g in one one mole. In such a way, since it is diatomic, we can notice that one mole of B2, is having 28 g of B2, as monoatomic atomic mass is considered twice.

Regards.
