You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
take the mass number of boron-10 and subtract the atomic number then divide that number by mass number then multiply it by 100
It depends on the mass of the starship in question.
The mantle is substantially larger than the Earth's crust. The crust varies in thickness, anywhere from 5-70 km, while the mantle measures at about 2900 km. Also, while the crust accounts for less than one percent of the Earth's over all volume, the mantle makes up a hefty 84%.
Most convection currents exist in the mantle, the layer below the Earth's crust. As the semi-molten rock heats up, it rises closer to the surface, and it sinks as it cools. This is how plate tectonics works, as the crust's plates move on these currents.
I dont think there can ANY earths that can be the mass of mecury. mercury is smaller than earth

Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
8%
If you're question is referring to finding a percentage once you already have the mass, then all you do is multiply the mass by the percent. Since percent is always out of 100, you divide your percent by 100 to get a decimal form (for example 92% becomes .92). Since calculators don't usually allow for a percentage sign, you take your new-found decimal and multiply it by your mass. I hope this helps
using the tables in the links below (and a little math), to match the diameter of the Sun would take about 109 Earths, to match the mass of the Sun it would take about 332,948 Earths, to match the volume of the Sun it would take about 1.3 million Earths (I think the hexagonal packing method is used here, cubic packing would be a few thousand less)
Convection currents take place in the mantle.
what causes all of the changes that take place in earths atmosphere is the tilt of the earths axis

Multiply .3631 and 1.185 together and take that answer and multiply it by 175. That's your answer.
In terms of volume, 1320 Earths.
