The density of gold is 19.3 g/cm3. What is the volume of a 13 g gold nugget? (Density: D = )

so the unit of densiy can be rewritten as g/mL  you are given a volume in Liters just convert it to mL using the relationship 1000mL = 1 L  0.00369 L(1000 mL/ 1 L) = 3.69 mL  then multiply the volume in mL to density, you'll get the mass  19.3 g/mL (3.69 mL) = 71.2 g
