In grams the body weight is measured in any physical state, and in milliliters - liquid volume. The mass of substance depends on its density which, in turn, depends on physical and chemical properties of substance and external conditions. Let's understand how to bring these physical quantities into accord.
It is required to you
- - calculator,
- - scales,
- - barometer,
- - thermometer,
- - reference book on physics.
Instruction
1. Determine substance weight in grams. Use for this purpose scales. Many foodstuff is sold by packaged. In this case the question of weight disappears in itself. For example, in a standard pack of granulated sugar, this foodstuff exactly one kilogram.
2. Find density of the necessary substance in the reference book on physics. For obtaining more exact result of the subsequent calculations, use adjustments for pressure, humidity and air temperature which are available in the reference book.
3. The value of density of substance in the reference book can be given in various units. If density is specified in kg/CBM - translate value of density in / cubic ml. For this purpose transfer cubic meters - to milliliters. Then substitute the corresponding units in numerator and a denominator, and increase by them tabular value of density: density (from the table) * 1000 / 1 000,000 ml.
4. By means of the calculator calculate substance volume: divide weight into density. Do not forget about units of measure! The received value will also define a ratio of mass of substance in grams to its volume in milliliters.
