How many teaspoons are in 70 mg?
One liter of water weighs exactly one kilogram. (This only true of water, oil, for example, weighs less.) There are 1000 ml (milliliters) in one liter, so one milliliter weighs one gram (not milligram!) and one gram is 1000 milligrams; therefore one milliliter is 1000 milligrams. There are then 0.07 milliliters in 70 milligrams.
Is it possible to convert milligrams per liter to milligrams per kilogram using the bulk density of a soil?
Yes, it is possible to convert milligrams per liter (mg/L) to milligrams per kilogram (mg/kg) using the bulk density of a soil. You would first need to determine the volume of soil in one kilogram using the bulk density, then use this volume to convert the concentration from mg/L to mg/kg. The formula for this conversion is: mg/kg = mg/L x (1000 / bulk density in g/L).
Is Chilling a liquid will increase evaporation at the surface true or false?
It is not true.
When water freezes it contracts true or false?
