120 mg x 1 g/ 1000mg = 0.12 grams
Just add the two masses: 40 + 120 = 160 grams.
The number of neutrons in an atom of mercury depends on the isotope. The most common mercury isotope has 122. The average number of neutrons in an atom of mercury is about 120.
120 g
The mass of 120 mL of water is 120 g.
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?
Density = Mass/Volume = 120 grams/7 ml = 17.142857... grams per ml.
cubic centimetres is volume not weight. if it is water then it would weight 120 grams
The only way to answer this is to know what substance you are measuring. Tablespoon is a measurement of volume (15 ml) and gram is a measurement of weight. 120 grams of water would fill a volume of 120 ml or 8 tablespoons whereas 120 grams of salt (which is about 2.1 times denser than water) would only fill about 3.8 tablespoons.
120/200=0.6 grams per cc
160 grams
Density = Mass/Volume so the density is 120/40 grams per cm3 = 3 grams per cubic cm.
120/200 = 3/5 = 0.6 g/cm3
This is not a valid conversion. Milliliters (mL or ml) and liters (L) are measures of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
120
There is no sensible answer to this question. A millilitre is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information. A little thought will make it clear that 1 gram of air will occupy far more volume than 1 gram of lead, for example.
120 ml of water weighs 120 grams
