Question

calculate number of oxygen molecules present in 10 moles of oxygen molecules

Plz reply

Answer 1

Answer:

A mole of oxygen molecules contains 2 moles of oxygen atoms. For elements that exist as molecules, it is best to explicitly state whether molecules or atoms are meant. Thus "1 mole of oxygen molecules" means 6.022 x 1023 O2 molecules, or 2 x 6.022 x 1023 O atoms; "1 mole of oxygen atoms" means 6.022 x 1023 O atoms.

Answer 2

Answer:. as 1 mole oxygen molecule contains 6.023 X10 raise to power 23 molecules so

10 moles of oxygen molecules has.

6.023 X10 raise to power 24 molecules

sorry if wrong
