Question

If one mole were to contain one i 1 into 10 to power 24 particles the mass of one molecule of oxygen would be

Answer 1

Answer:

53g

According to question 1 mole contain 10^24 molecules.

Avogadro number=6.022× 10^23.

Atomic mass of Oxygen=16u

Therefore molar mass of Oxygen=32u

Number of moles= Given number of molecules ÷ Avogadro number

10^24 ÷6.022×10^23

Mass=molar mass× number of moles

= 32 × 10^24÷ 6.022 × 10^23

= 53 g

Answer 2

answer: 53.1g

explanation:

6.022x10^23 molecules of 02--weighs 32g

1x10^24 molecules of 02= 32x10^24

------------------ = 53.1g

6.022x10^23
