HOW TO GET percent of magnesium by mass?
You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
What percent of the mass of the isotope boron-10 are neutrons?
take the mass number of boron-10 and subtract the atomic number then divide that number by mass number then multiply it by 100
How much energy does it take a spaceship to travel at constant speed 90 percent of light speed?
It depends on the mass of the starship in question.
How much larger is the mantle then the crust?
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%.
Where does heat transfer by convection currents take place in the earths interior?
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.
How many earths would it take to equal the mass of mercury?
I dont think there can ANY earths that can be the mass of mecury. mercury is smaller than earth

What is percent abundance?
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
What is the percent of the land mass tropical rainforests take up?
8%
How do you find the percent of a mass?
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
How many Earth's would it take to match the Sun?
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)
Where in the earth do convection currents occur?
Convection currents take place in the mantle.
What causes all of the changes that take place in earths atmosphere?
what causes all of the changes that take place in earths atmosphere is the tilt of the earths axis
What percent of the mass of the isotope boron-10 are neutrons?
take the mass number of boron-10 and subtract the atomic number then divide that number by mass number then multiply it by 100
When a concentrated hydrochloric solution is 36.31 percent hci and 63.69 percent h20 by mass its specific heat is 1.185 what mass of pure hci is concentrated in 175 ml of this solution?
Multiply .3631 and 1.185 together and take that answer and multiply it by 175. That's your answer.
How Much Earths does it take to make Jupiter?
In terms of volume, 1320 Earths.
