Question

what
is mass of:
O. 2
mole
of
oxygen atoms?​

Answer 1

Answer:

o calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.

So as we know that one mole of oxygen has mass of 16 gram than of 0.2 moles will be

0.2 . 16=3.2gram

Answer 2

Answer:

1 is the mass of the molecule O2
