Answer:
2.01
Explanation:
The effusion is the passage of the molecules by a small hole by a difference of pressure. By Graham's Law, the rate of the effusion is inversely proportional to the square of the molar mass of the compound. Thus,
rateHF/rateHBr = √MHBr /√MHF
MHBr = 81 g/mol
MHF = 20 g/mol
rateHF/rateHBr = √81/√20
rateHF/rateHBr = 2.01
Gravitation Potential energy is converted into the Kinetic Energy, when it just reaches the ground. Some amount of energy is wasted in sound and heat energy when it strikes the ground. When the apple falls from the tree, it has some gravitational potential energy due to its height.
M
350 mL = 0.350 L
245.0g H2SO4 / 98.08 g/mol H2SO4
= 2.5 mol H2SO4
2.5 mol H2SO4 / 0.350 L = 7.14 M
