Answer:
Please find the solution in the attached file.
Explanation:
Answer:It has the lowest effective nuclear charge of the four new elements.
Mole is equal to 6.02*10^23 atoms, and you have 7.00*10^23 atoms
M = 22.8 g
V = 14.7 mL
ρ - ?
ρ = m/V
ρ = 22.8/14.7 = 1.55 g/mL
The molar concentration will be greater than 0.01 M
.
Since more of the compound was measured out than what was calculated, you can think of the solution as being 'stronger' than what it was calculated to be. Since a 'stronger' concentration results in a number that is higher, the molarity of this solution is going to be greater than 0.01 M.
