If you have a ratio (A/B) ... (you know the numbers 'A' and 'B') ... write the equation
x / 1,000,000 = A/B
and solve it for 'x'. 'x' is the ppm. Here's what the solution looks like:
Multiply each side by 1 million:
x = 1,000,000 A / B
and there you have it.
Convert them to fractions.
Ppm stands per parts per million. There are 1,000,000 micrograms in a gram. Therefore micrograms per gram is already ppm.
Convert all ratios to percentages or decimals (as you like) and then compare them.
Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L) Extract the data from the question: mass solute (NaCl) = 0.0045 g. ... Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.
To convert a ratio you turn it into a fraction or a different way of writing the ratio. For example, 6 to 5 could also be written as 6/5 or 6:5.
0.5Mm = 50 PPM
Multiply ppm by 10000.
322 ppm = 0.0322%
1 GPG = 17.1 PPM
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
*1000
ppm x 3to the power of 6= kg
Divide ppm by 10,000:50,000 / 10,000 = 5 %
Divide by 1000.
Multiply by 10,000: 0.0025 x 10,000 = 25 ppm
10 ppm mole multiply by molecular weight of water then divided by sample density
You cant...Coz its not a ratio...You can find number of moles, weight, and etc but not ppm bcoz ppm is termed from composition
