1 liter = 1000 cc = 1000 cu cm
0.386 g /1 mL = 0.386 g / 1000 cc = 3.86 x 10-4 g/cc
the second question, about speed of light, got chopped off; I do recall that c = 31010 cm/sec = 186,000 mi/sec

Actually, 1 cubic cm is equal to 1 ml. So 0.386 g/ml is the same as 0.386 g/cm3. I think Kenneth just misread the question.

The question statement is incorrect. The density of copper is 8.94 g/cm³ not 0.386 g/cm³ (a cm³, a cc, and a ml all being roughly the same value)03/20/22
