40kg of mass, 400 (approx) N of weight.
The weight of water is approximately 8.34 pounds per gallon. Since there are roughly 3.785 liters in a gallon, 40 liters of water would be equivalent to about 10.57 gallons. Multiplying 10.57 gallons by 8.34 pounds per gallon gives us a weight of approximately 88.39 pounds for 40 liters of water.
Weight is related to an objects mass and acceleration due to gravity not its volume.
If the mass of the barrel is 40 kilograms and the barrel is presently on earth, then it weighs 392 newtons (88.2 pounds). What you do with it, what dizzying gyrations you subject it to, or what other objects happen to be nearby, have no effect on its weight.
While just holding the weight on his shoulder, the weight lifter does no work! For work to be done, the mass must be moved through a distance … No Movement, No Work! (but don't tell that to a weight lifter …)
To determine the mass of 40 ml of a substance, you need to know its density, as mass is calculated using the formula: mass = density × volume. For example, if the substance is water, which has a density of approximately 1 g/ml, then 40 ml of water would have a mass of about 40 grams. If the density is different, you would use that specific value for calculation.
The weight of an object is the force exerted on it due to gravity. On Earth, the weight of an object can be calculated by multiplying its mass by the acceleration due to gravity (9.8 m/s^2). Therefore, an object with a mass of 40 kg would weigh approximately 392 N on Earth.
The weight of a 40 kg student on Earth can be calculated using the formula W = mg, where W is the weight, m is the mass, and g is the acceleration due to gravity (g = 9.81 m/s^2). Plugging in the values, the weight of a 40 kg student on Earth would be approximately 392.4 N.
You need to multiply the mass with the value of gravity; near Earth's surface that value is approximately 9.8 newton/kilogram.
The 40kg student's force (weight) on Earth is about 392.28 newtons. (Force = mass x acceleration). Earth's acceleration is 9.807 meters per second squared.
What planet are you on? I don't mean to be a wise-ass, but weight depends upon the acceleration of gravity, which is different on different planets, whereas mass is the same no matter where you are. On the surface of the Earth, the acceleration due to gravity is 9.8 m/s2, so a 40-kg mass will weigh 40 x 9.8 = 392 newtons.

On Earth, 40 kg of mass weighs 88.185 pounds. (rounded) In other places, the same 40 kg has a different weight in pounds.
40 kg IS a measurement of mass. In avoirdupois weight that's 88 lbs.
