Which of the following would not be acceptable units for density?
Answer
kg/L
g/mL3
g/cm3<< my answer
Density has units of mass/volume.
kg/L is a mass/volume
g/cc is a mass/volume
g/mL is a mass/volume but g/mL3 is not.
Your answer is correct. The unit "g/cm3" would not be an acceptable unit for density. Density is defined as mass per unit volume, and the acceptable SI units for density are kg/m3 or g/cm3.
To determine which of the given units would not be acceptable for density, you need to understand the concept of density and the and the rules for appropriate unit conversions.
Density is a measure of how much mass is contained within a given volume. It is calculated by dividing the mass of an object or substance by its volume. The SI unit for mass is kilograms (kg), and the SI unit for volume is cubic meters (m^3).
Now let's analyze the options:
1. kg/L: This unit is acceptable for density. Here, the mass is in kilograms (kg), and the volume is in liters (L). To use this unit, you can simply divide the mass in kg by the volume in liters to obtain the density in kg/L.
2. g/mL3: This unit is not acceptable for density. The reason is the exponent "3" attached to mL. The correct unit for volume in the metric system is cubic meters (m^3), not mL^3. Additionally, the unit for mass is grams (g), which is correct. To use the correct unit, you would need to convert the volume from mL to cubic meters.
3. g/cm3: This unit is acceptable for density. The mass is in grams (g), which is correct, and the volume is in cubic centimeters (cm^3). To use this unit, you can divide the mass in grams by the volume in cubic centimeters to obtain the density in g/cm^3.
Based on this analysis, the unit that would not be acceptable for density is g/mL3.
