In chemistry, what varies with the number of molecules present in a sample of a particular substance?
Neko [114]

Answer: concentration

Explanation:

Concentration refers to the amount of a substance present in a sample. The more molecules of a substance present in a sample, the greater its concentration. The less molecules of a substance in a sample, the lesser the concentration. We are often concerned about analytically determining the concentration of a substance using diverse analytical methods in chemistry.

a certain piece of copper wire is determined to have a mass of 2.0 0g per meter how many centimeters of the wire would be needed
harina [27]

The given question tells you that a certain piece of wire has a mass  = 2.0 g per meter

That means that if you consider a piece of wire that is 1 m in length, its mass will be equal to  2.00 g .

According to question,

Now, you know that

1 m = 100 cm

Mass of  2.00 g  of copper will correspond to a wire that is a 100 cm long.

This implies that  0.28 gof copper will correspond to a wire that is

0.28 g * 100 cm /  2.0 g = 14 cm long

Hence, 14 cm of the wire would be needed to provide 0.28 g of copper.

Properties of Copper :

High conductivity and ductility.

Non magnetic.
