What else can I help you with?
Why do scientist use weighted average instead of straight mathematical average of masses of isotopes to indicate the atomic mass of an element?
The percentage of each isotope is different.
Between mass and weight which is dependent on the other?
Weight is dependent on mass. Weight is the force exerted on an object due to gravity, and it is directly proportional to an object's mass. Mass, on the other hand, remains constant regardless of location in the universe.
What scientist did the law of conservation of mass?
The law of conservation of mass was formulated by the French scientist Antoine Lavoisier in 1789. He demonstrated that in a closed system, the total mass remains constant in a chemical reaction, even if the substances change form.
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
Does mass affect the weight?
Yes. For most purposes, weight is a constant multiple of mass.
Why do scientist prefer to describe matter by it's mass rather than its weight?
Mass is how much space an object takes up. While weight is just how heavy it is.
What does it mean to say mass and weight are proportional to each other?
Saying mass and weight are proportional means that as mass increases, weight (the force due to gravity acting on the mass) also increases in direct proportion. This relationship is described by the equation Weight = mass x gravitational acceleration.
Why don't scientist use weight instead of mass as a measurement?
Weight is not a physical property of an object, it is an effect, which varies from place to place. A given object will have the same mass no matter whether it is on the Earth, or on Mars, or somewhere in between.
Does the shape of an object determine mass?
No. Mass is the weight of an object on earth. Scientists use mass instead of weight so the measurements will be the same everywhere. For example A big ballon has a relatively lower mass than a small sized stone
Why do scientist use mass instead of weight?
The word weight in every day speech means how much do you weigh converted back to mass. That is if I ask "what do you weigh?" but I want the answer in pounds or kilograms.In science mass is measured in kilograms (or pounds outside the science lab) but weight has more to do with the gravitational pull of the Earth.Newton's second law is F = maForce = mass x accelerationWeight = mass x acceleration due to gravityW = 50 kg x 9.8 m/s2 (Force or Weight has a unit of Newtons, N)= 490 NWhy? Perhaps because when we use the balance or the weighing machine we are using gravity but then we convert the scale back to mass.
How do you convert units of weight and mass?
In the metric system (really called SI) weight is measured in units of newtons (lower case n to emphasize we are not talking about the scientist) and mass is in units of kilograms. W = mg (g =9.8) so weight in newtons equals mass in kilograms times 9.8.
How do you find the weight when mass and volume is given?
Weight = Mass *Accelerationdue to Gravityw = mg, where g~=9.81 m/s^2If you, instead meant to ask for density (d):d = mass / volumed = m / v
Why do scientist measure and record the mass other than the weight?
The mass is a measure of the amount of matter present in an object whereas weight is a measure of the force on the object due to gravity. Weight is measured in Newtons, mass is measured in kilograms (pounds in the Imperial system) When we use the term weight outside of science we actually are referring to mass. mass is a measure of 'stuff,' of material that makes up an object. weight is the gravities affect on mass as you can see from the equation Fg=mg, m=mass g=gravity (on earth it is 9.8) and fg is weight in newtons
What is a mass of a rubber?
The mass of any object is its attraction by gravity. If the ball is attracted by gravity, and the attraction is measured by scales, we might say that the ball has a weight of five kilograms, or a mass of five kilograms. We can put it another way by saying that mass is the property of a body that causes it to have weight in a gravitational field.
Why is mass more useful than weight for measured matter?
Scientists prefer to rely on mass instead of weight when measuring because weight will change depending on location, whereas mass remains constant regardless of location. You could weigh 60 pounds on earth, but 10 pounds on the moon, but your mass would be the same on earth and the moon.
Why might scientist measure the mass of an object rather than the weight of an object?
The mass of an object does not change , but its weight can vary.
Why do you use mass and not weight in science?
In science, mass is used instead of weight because mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on an object. Mass remains constant regardless of location, while weight can vary depending on the gravitational pull. By using mass, scientists can ensure consistent measurements and comparisons across different environments.
