I hope this helps, sorry if it doesnt. Not really good with chemistry, hope you have a great day/night :}
Explanation:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance.
12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
1) N = 4,2 moles
M = 24,31 u
m = N x M
= 4.2 x 24.31 = 102.102 kg
2) m = 54.9 grams = 0.0549 kilograms
M (Na) = 22.99 u
N (moles) = m / M
N = 0.0549 / 22.99 = 2.4 x 10^-3 moles
I don’t know if it helped you a bit :)
