All Answers (16) 1 ppm = 1 part /106 part; 1% = 1/100; so 1% = 1/100 x 106 = 104 ppm. If each element is available in wt%, just multiply with 104 to get the concentration numbers in ppm.

The standard formula is C = m/V, where C is the concentration, m is the mass of the solute dissolved, and V is the total volume of the solution. If you have a small concentration, find the answer in parts per million (ppm) to make it easier to follow.

Divide by the Total Mass Divide the mass of solids by the total mass of the solution, and then multiply the result by 100 to calculate the percentage of solids by weight.

A) Converting from atomic percent to weight percent: 1. For each element listed in the compound, multiply the atomic percent of the element by its atomic weight [the larger of the two principal numbers listed for each element in the standard periodic table]. For each element, lets call this value p.

The conversion factor would be 1 mg/l = 3 NTU = 1 ppm based on 1 mg/l = 1 ppm. Each application may have a different conversion factor due to the varying response of the turbidity instrument based on the particulars of the application and samples.

FPKM can be easily converted to TPM by dividing the each FPKM value by the sum of all FPKM values of the respective sample, and multiplying this by 1e6. This yields TPM.

PPM is a term used in chemistry to denote a very, very low concentration of a solution. One gram in 1000 ml is 1000 ppm and one thousandth of a gram (0.001g) in 1000 ml is one ppm. One thousanth of a gram is one milligram and 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter.

Follow the following equation to determine your goal weight: First, subtract your desired body fat percentage from 1. For example, if your desired percentage is 20 percent, subtract 0.20 from 1. Then, divide your lean body weight by this figure. This number is your goal body weight.

Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated.

To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent.
