All the solar energy is generated in the core by nuclear fusion. Around the core there is the radiative zone. ... It extends from a depth of 200,000 km up to the visible surface of the Sun. Energy is transported by convection in this region. The surface of the convection zone is where light (photons) is created.
Answer: Potassium is 39.10 g/mol
Explanation: The numbers below the element are the molar mass.
6.02 x 10^23 moles of representative particles
Well, think of it this way. If you put a big paper circle on the ground, and then you put smaller circles on top of the big circle, which one would have been there longer? The big circle, of course. So the same logic applies here: if the smaller craters had been older than the big crater, then when the big crater was formed, the smaller ones would've been buried. Therefore, crater 2 is older than the smaller craters inside it.
Hope that helped! =)
