Final answer:
To calculate the density, divide the mass by the volume. Given a mass of 1kg and volume of 125 cm³, the density is 8g/cm³.
Step-by-step explanation:
To calculate density, we divide the mass by the volume. Given that mass is 1kg and volume is 125 cm³, we can calculate the density in grams per cubic centimeter (g/cm³).
Since 1 kg = 1000 g and 1 cm³ = 1 mL, we can convert the mass to grams and calculate:
Density = Mass/Volume = 1000g/125cm³ = 8g/cm³.
Therefore, the density is 8g/cm³, so the answer is a. 0.008 g/cm³.
