Final answer:
The density of zinc is given as 7.14 g/cm³ and to convert it to kg/m³ you multiply by 1000, which results in 7.14 x 10³ kg/m³. The correct answer is D) 7.14 x 10³ kg/m³.
Step-by-step explanation:
To convert the density of zinc from g/cm³ to kg/m³, you should know that 1 g/cm³ is equivalent to 1000 kg/m³. Therefore, if zinc has a density of 7.14 g/cm³, to express this in kg/m³, you multiply 7.14 by 1000. Doing this conversion gives you the density of zinc as 7.14 x 10³ kg/m³.
Multiplying by 1000 essentially converts grams to kilograms and cubic centimeters to cubic meters, effectively scaling up both the mass and volume units from the centimeter-gram-second (CGS) system to the International System of Units (SI).
The correct answer is: D) 7.14 x 10³ kg/m³.
