Question

What is the masa of 6×6.022×10^23

Answer 1

Step-by-step explanation:

6*6.022*10 ^23 of an oxygen molecules?

6*6.022*10^23 is the avogadro number, which equals 1 mole. so you are basically asking how much a mole of oxygen weighs. ...

Oxygen molecules mass is 32 since oxygen atoms atomic mass is 16. (16*2).

A mole of hydrogen atoms is 1g and the atomic mass of hydrogen is 1.

so the mass ration of the mole oxygen molecules and the mole hydrogen atoms is 32:1, which means a mole of oxygen molecules weighs 32g in totals.
