Answer:
Since Alice has a greater density it will also have a greater mass
Density = mass / volume
The potential energy at the surface of Alice will be greater and a higher kinetic energy will be required to escape the planet's gravitational pull.
PE = K M / R potential at surface is greater because mass is greater
KE = 1/2 M v^2 greater velocity required to overcome PE
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
The answer is 403 ml coz when you divide 0.403 with 1000 ml you get 403 ml
