3. Multiply the volume and density together. Multiply your two numbers together, and you'll know the mass of your object. Keep track of the units as you do this, and you'll see that you end up with units of mass (kilograms or grams). Example: We have a diamond with volume 5,000 cm 3 and density 3.52 g/cm 3.

A mass balance is only meaningful in terms of a specific region of space, which has boundaries across which the terms and are determined. This region is called the control volume. In our derivation of the mass balance equation, we have referred to the mass of pollutant in a lake and the fluxes of pollutant into and out of the lake---that is, we ...

7. When the reaction ends, pour out the water and weighed the mass of the mixture on the digital scale. Subtract this number and the mass of the salt from the original total mass will help you find the mass of the sand.

Answer (1 of 3): It depends. Do you mean a particular grain of sand? Or perhaps you mean a typical grain of sand from a specific place, or a certain sample. For a particular grain of sand, you need scale that can weigh it accurately, and a device for measuring volume. The first you can find in m...

The inventory (mass balance) control method, enhanced by the novel developments this industry has seen in the last two decades (sand mulling, core-and moldmaking, shakeout and sand reclamation) is promising and deserves to be studied, evaluated, developed and applied. However, the sand system itself is only one element of the larger foundry system.

Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

The melting point of salt is 1474°F (801°C), while that of sand is 3110°F (1710°C). Salt becomes molten at a lower temperature than sand. To separate the components, a mixture of salt and sand is heated above 801°C, yet below 1710°C. The molten salt may be poured off, leaving the sand.

The forms of channels and floodplains are largely determined by the stream-flow regime and the watershed sediment supply. When the supply of water and sediment to a river change, the river may respond by accumulating or evacuating sediment that in turn changes the attributes and availability of aquatic habitat.
