For theoretical exercises use pure water standard of 1 kilogram per liter or 1 gram per cubic centimeter (the same as milliliter). For practical and precise calc it must be considered other matters like temperature and water characteristics. Use the link below for calculations.
1 molecule of water = 3.10-23 g
Calculate the mass in grams of a single water molecule.
The mass is measured with balances; kilogram (kg) is the unit of mass in SI.
1 kg = 1 000 g
I assume the correct units for the density is 3.14 grams per milliliter. So if you have 93.5 grams of a substance with a density of 3.14 grams per milliliter, then you divide the mass by the density to find volume. 93.5 grams/3.14 grams/ml = 29.77 ml
1.54 moles H2O (18.016 grams/1 mol H2O ) =27.7 grams
denisity = mass/volume = 67.7 grams/12.8 mL = 5.29 g/mL
153 grams
This mass is 5,323 grams.
To find the mass, we divide by Avogadro's number to find the amount of moles. We then multiply the moles by the molar mass of the compound which is 60.08 grams. Doing all of this, we get a mass in grams of 5.59 grams.

Gram is a unit of mass. Just look at the number that comes before 'gram'. That's the mass, in grams.
the mass is the 50 grams you probably need the volume volume = mass / density get the density from tables
To find the answer, we multiply the 7 grams of NaCl by the ratio of the molar mass of chlorine over the molar mass of sodium chloride. By doing this, we find that there are about 4.25 grams of chlorine in 7 grams of NaCl.
Unfortunately, an animals kilometers are not a measure of mass. If you knew the volume of the animal and the density you could find the mass in grams.
People wanted to find out the exact amount of mass an object has. So people simplified kg into grams.
Grams. Matter is measured by mass and mass's main unit is grams.
You use grams to find the mass of an object.
