There is no equivalence.
A gram is a measure of mass, not a measure of volume. According to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider 120 grams of lead. What is the volume? Next consider 120 grams of air. What is the volume?
The density of the block of wood is 0.6 g/cm³. This is calculated by dividing the mass (120 g) by the volume (200 cm³).
Assuming the wood has a volume of 200 cm3 and not 200 cm as stated, its density is 120 g/200 cm3 =120/200 g/cm3 = 0.6 g/cm3
The density of the wood can be calculated by dividing the mass by the volume: density = mass/volume. In this case, density = 120 g / 200 cm^3 = 0.6 g/cm^3. The density of the wood is 0.6 grams per cubic centimeter.
The volume should be 200 cm3, not cm2. Density = Mass/Volume = 120g /200 cm3 = 0.6 g/cm3
120/200 = 3/5 = 0.6 g/cm3
density = mass / volume so d= 120g / 200cm^3 d=0.6 g /cm^3
The mass can be calculated by multiplying the volume by the density. Mass = volume x density, so in this case, mass = 120 mL x 0.75 g/mL = 90 grams.
120 mg = 0.12 g
120 ml
It is the same as: 2.5*120 = 300 g
There are 0.120 g in 120 mg. 1 g = 1000 mg 1 mg = 0.001 g
1,000 mg = 1.000 g 100 mg = 0.100 g 120 mg = 0.120 g
