Salt Production and Processing - Morton Salt

Salt may appear in veins, as does coal. Veins are the original bedded salt deposits. Salt also may be found in domes, which were formed when Earth pressures forced salt up through cracks in the bedrock from depths as great as 30,000 or 40,000 feet; they resele plugs of almost-circular shape a few hundred yards to a mile across.

Chemical Equations and Calculations

Calculate the mass ratio of CH 4 to O 2 required for complete coustion. Solution: This is just the ratio of the molar mass of CH 4 (16 g) to that of two moles of dioxygen (2 x 32 g) Thus (64 g) / (16 g) = 4/1 = 4.0. Complete coustion of each kg of methane consumes 4 kg of dioxygen, which is supplied by the air.

Density Formula - How To Calculate Density

22/8/2019· Density is often written in mathematics as the syol p or D. Mass can be written as m, and volume can be written as V. So if you want to be fancy, the formula looks like this: p = m/V (Volume is to do with filling space: check out our guide to volume and weight and our volume calculator if you''re not yet confident with it.)
