Question

The mass of 1 mole of neutrons( mass of neutron=1.675×10^-27)

Answer 1

Mass of one neutron= 1.675×10^ -27 amu.
Mass of one mole neutrons=1.675×10^-27×6.02×10^23=10.0835×10^-4 amu.

Answer 2

Given:

Mass of neutron = $1.675\times 10^{-27}$

To find:

Mass of 1 mole of neutron = ?

Formula to be used:

Mass of 1 mole of neutron =$Mass of neutron\times Avogadro's number$

Calculation:

Mass of 1 mole of neutron = $Mass of neutron\times Avogadro's number$

Mass of 1 mole of neutron = $(1.675\times 10^{-27})\times (6.022\times 10^{23})$

Mass of 1 mole of neutron = $10.086\times 10^{-4}$

Conclusion:

Thus the mass of 1 mole of neutron is calculated as $10.086\times 10^{-4}$
