Jupiter has greater gravitational pull than earth, about 2.4 time greater than that of earth. This means that a person weighing 100 pound on earth will weigh 240 pounds on Jupiter.
Jupiter is the largest planet in the solar system. It is so large that all other planets would comfortably fit inside it. It is over 1000 times bigger than the earth.
Jupiter is the fifth planet from the sun and rotates faster than any other planet. A day in Jupiter is about 10 hours long.
Answer:
there are approximately n ≈ 10²² moles
Explanation:
Since the radius of the earth is approximately R=6378 km= 6.378*10⁶ m , then the surface S of the earth would be
S= 4*π*R²
since the water covers 75% of the Earth's surface , the surface covered by water Sw is
Sw=0.75*S
the volume for a surface Sw and a depth D= 3 km = 3000 m ( approximating the volume through a rectangular shape) is
V=Sw*D
the mass of water under a volume V , assuming a density ρ= 1000 kg/m³ is
m=ρ*V
the number of moles n of water ( molecular weight M= 18 g/mole = 1.8*10⁻² kg/mole ) for a mass m is
n = m/M
then
n = m/M = ρ*V/M = ρ*Sw*D/M = 0.75*ρ*S*D/M = 3/4*ρ*4*π*R² *D/M = 3*π*ρ*R² *D/M
n=3*π*ρ*R² *D/M
replacing values
n=3*π*ρ*R² *D/M = 3*π*1000 kg/m³*(6.378*10⁶ m)² *3000 m /(1.8*10⁻² kg/mole) = 3*π*6.378*3/1.8 * 10²⁰ = 100.18 * 10²⁰ ≈ 10²² moles
n ≈ 10²² moles
LiNO3; nitrate has a charge of -1, and lithium has a charge of +1
Heat is energy, that can be transferred to another item, which is “less hot”.
