The density of diamond is 3.51 g/cm3 . the international (but non-si) unit for weighing diamonds is the "carat" (1 carat = 200 mg exactly.) what is volume of a 0.87 carat diamond? answer in units of cm3 .

To calculate the volume of the diamond, we use the formula

Here, is the density and its value given

and m is mass and its value given.

1 carat = 200 mg = 0.200 g

So mass of the diamond,

Substituting these values in above equation we get,

Thus the volume of given carat diamond is .

i think the answer is a, hope this is right, that would be my best guess.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
