Explanation:
Im not sure what the other trait is so I couldn't do phenotype. I hope this still helps though
Answer:
N = n× l
N = number of entities
n= moles
l = Avogadro's constant = 6.023 × 10^23
3.01 × 10^ 23 = n * 6.023 × 10^23
n = 3.01 × 10^23/6.023 × 10^23
n= 0.5moles
Molar mass = mass/ number of moles
Molar mass = 56
mass = 56 × 0.5
= 28g
Hope this helps.
If you change the subscripts it would change the reactants or products and then you would be solving a different formula, you would change what the chemical is
Llowing certain substances to pass through it but not others, especially allowing the passage of a solvent but not of certain solutes.
