No mars is mostly made up of carbon dioxide, which makes up 95.32% of the atmosphere
Neptune's atmosphere is made up of 80-percent hydrogen, 19-percent helium, and 1-percent methane. Methane is part of what gives Neptune its brilliant blue tint, as it absorbs red light and reflects bluer colors.
Yes, Mars does have traces of hydrogen in its atmosphere. The presence of hydrogen on Mars has been detected through various observations and scientific instruments, including the Mars Atmosphere and Volatile Evolution (MAVEN) mission. However, the amount of hydrogen on Mars is relatively small compared to other elements.
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
Saturn doesn't have a surface per se, but rather is a ball made up of hydrogen and helium. Hydrogen makes up 75 percent of the planet's atmosphere.
The percent by mass of hydrogen in NH3 is 17.65%. This can be calculated by dividing the mass of hydrogen in NH3 by the total mass of NH3 and then multiplying by 100.
Yes
Uranus is a gaseous, frozen planet that has a molten core. It is made up of 83 percent Hydrogen, 15 percent Helium, and 2 percent Methane.
70 percent of 83 percent is 0.581 or 58.1%
83%
83 percent of 335 is 278.05
83 percent of 12 is 9.96
83 percent of 410 is 340.3
83 percent of 220 is 182.6.
83/100 = 83%
83%.
Expressed as a percentage, 83/100 x 100 = 83 percent.
83% = 83/100
