Question

Suppose a chemist has chosen
${10}^{20}$
as the number of particles in a mole. Then the molecular mass of oxygen is

$5.32 \times {10| }^{ - 3}$
$53.2 \times {10}^{ - 3}$
$0.532 \times {10}^{ - 3}$
$532 \times {10}^{ - 4}$
​

Answer 1

Answer:

1)

Explanation:

the MOLECULAR mass of O2 would still = 32 AMU  

.. the MOLAR mass of O2 would be different though  

.. . .. (32 AMU / molecule) x (1.66x10^-24 g / AMU) x (10^20 molecules / mole)  

.. ... .= 5.3x10^-3 g / mole
