It has the highest atomic number so it would have more shells, making it larger than the others.
Answer:
mass = 6.56 grams
Explanation:
No of molecules = No of moles × Avogadro's constant
Similarly, number of moles = mass/ molar mass
∴
mass = 6.56 grams
Answer:
0.5 M
Explanation:
Molar concentration : M = n/v
n = moles of solute
v = liters of solution
Hence, 5.0 / 10.0 = 0.5 M
I think C. 0.3
Sorry if wrong :)
