Weight(W)=mass(M)* acceleration due to gravity(g) which is =9.8ms^2 therefore,weight of 40kg is w=40 * 9.8 w=392N
density = mass/volume = 40/20 = 2 g/cc
The question doesn't make sense, 40g weighs 40g. Do you mean what does 40g equate to in an other system of measures?
Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
If a student's mass is 40kg on earth, then his mass is 40kg wherever in the universe he goes. Mass doesn't change. What changes is the gravitational force between each mass and the other masses in the vicinity of the first one. That force is what we call "weight".
40kg

40kg of mass, 400 (approx) N of weight.
40g
density = mass/volume = 40/20 = 2 g/cc
Density = 2 g/cm3
20 g/ml
This depends on the density of the solution and density depends on the concentration of sugar.
40kg = 6.29892178 stone
You multiply the mass by the gravity. Normal Earth gravity is about 9.8 (in meters/second2, or the equivalent newton/kilogram).
Since the gram atomic mass of calcium is 40.08 and calcium does not form polyatomic molecules, the number of moles in 40g of calcium is 1.0, to the justified number of significant digits.
2g per cm3
