The purpose of this question is for you to calculate the density of the objects and compare their density to that of water. If less than water the object will float, if more than water the object will sink.
density = mass/volume
You have mass and volume of each. Calculate density. Then look up the density of water at 3.98 degrees C and compare. Post your results if you want us to check them.
1 what si the diference between mass and weight?
2 will the following substances float or sink in water at 3.98 degree celcius?
Mass volume float & sink
25g 50ml ?
65g 40ml ?
36g 35ml ?
6 answers
thanks ....is it like...
25g 50ml float 0.5
65g 40ml float 1.625
36g 35ml float 1.0285
25g 50ml float 0.5
65g 40ml float 1.625
36g 35ml float 1.0285
and ya 1 more question

You calculated the density correctly for all three objects. What did you compare it with to get your three answers of float, float, float?

I'm not entirely sure but I think the main difference is that mass is used in relation to the metric system (metric syst. is used universally in compiling data from scientific findings)and I think weight is used in the customary system.
LOL! All I remember is our Chem teacher telling us "we don't weigh things in here, we mass it"
Ugh....! I HATED chemistry with a passion!!

Mass vs. Weight: Although the terms mass and weight are used almost interchangeably, there is a difference between them. Mass is a measure of the quantity of matter, which is constant all over the universe. Weight is proportional to mass but depends on location in the universe. Weight is the force exerted on a body by gravitational attraction (usually by the earth).
Example: The mass of a man is constant. However the man may weigh: 150 lbs on earth, 25 lbs on the moon (because the force of gravity on the moon is 1/6 that of the earth), and be "weightless" in space.
