The formula for calculating density, D, is =/, where M represents mass and V represents volume. For liquids, volume is often given in cubic centimeters (cc),which is the same as cm3. If the density of an unknown liquid is 2.1 g/cc, what is the mass of 400 cc of the unknown liquid in grams (g)? *
A. 840g
B. 190g
C.005g
D. 8.4g
