How many mg are in 50 micro grams
0.5mg
How many mg are found in 50 Grams
50,000mg
What does 1:100,000 mean
Grams per ml
How many mg of epi is found in 3ml of 1:1000
3mg (do the calculation)
How many mg per ml for 0.9%, 0.5%, 2%

How do you calculate concentration
Concentration= amount\ volume
How do you calculate amount
Amount= Concentration x volume
Solution
mixture of two or more substances
Solute
substance that is dissolved in a solution
Solvent
substance in which the solute is dissolved, present in the greatest amount
Technically why are pounds and Kg not be equated to each other
pound is a unit of weight not mass
K =
K= C + 273
Convert F to C
F= 9\5 + 32 or F= (1.8 x C) + 32
Convert F to Celsius
((F-32) x 5)\9 = C
Density and its equation
the ratio of mass of an object to its volume, p=d=mass (in grams) \volume (in ml)
Water has a density of
1g \ml 8.33pounds\gallon
specific gravity
the ratio between an objects density and the density of water, (any sample with a specific gravity greater than 1 is denser than water
