Answer to Question #158648 in General Chemistry for teeeeeera

Question

The mass of a neutron is 1.67×10^-24 g. How many neutrons would be needed to have the same mass as a salt crystal with a mass of 2.50×10^-2 g?

.............................neutrons

Answer 1

The number of neutrons required to have the mass of 2.50×10^-2 g equals:

n(neutrons) = (mass of neutrons) / (mass of one neutron) = 2.50 × 10^-2 g / 1.67 × 10^-24 g = 1.50 × 10²²

Answer: 1.50 × 10²² neutrons
