Copper has a density of 8.92 g/cm^3. a sample of copper occupies a volume of 25.8 ml. what is the mass of this sample of copper in milligrams?

Given:

Density:8.92g/cm3

Volume:25.8 mL

Now we know that

Mass = density X volume

Substituting the given values in the above equation we get:

Mass = 8.92 x 25.8= 230.136 g

= 230136 mg

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
