There is no gravity and gravity pulls things down
Answer:
the energy required to do work
The standard atomic weight of a C is 12, and the standard atomic weight of a H is 1. So to find molar ratio of C and H in the compound: 60.0/12=5, 5.05/1=5. This means the molar ratio of C and H is 5:5, thus 1:1. Assuming the molecular formula is CnHn, to find molar mass: 12n + 1n = 78.12. n=78.12/(12+1) = 6. So the compound's molecular formula is C6H6, benzene.
Answer is: the pressure on the top of the mountain is 0.945 atm.
p₁ = 1.0 atm; pressure at the valley.
T₁ = 25°C = 298.15 K; temperature at the valley.
V₁ = 0.985 L; volume at the valley.
p₂ = ?
T₂ = 22°C = 295.15 K; temperature at the top of the mountain.
V₂ = 1.030 L; volume at the top of the mountain.
Use combined gas law - the volume of amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.
p₁V₁/T₁ = p₂V₂/T₂.
1 atm · 0.985 L ÷ 298.15 K = p₂ · 1.030 L ÷ 295.15 K.
0,0033 atm·L/K = 0.00349p₂.
p₂ = 0.945 atm.
