2013年5月28日 · If it is millions of gallons per day, then multiplication by 8.34 lb/gallon gives millions of pounds (of water) per day, and the dosage in mg/L can be interpreted as parts per millions (again with some assumptions), and is correct. If M is used to represent thousand, the formula is grossly wrong (by 1000X, more or less)

2007年12月6日 · I have the average abundaces of Fe, Si, N, and P in seawater in mg/l but would like to convert to micromol to compare them with other values I have. Here are the numbers: Nitrogen: 11.5 mg/l (as N2, NO3, and NH4)(total amt in the ocean in tonnes: 1.50E13) Silicon: 2 mg/l (as Si(OH)4) (total amt:2.64E12)

2019年1月20日 · Could someone please explain the steps to convert mg/L to % (w/w) with the details below; weight of sample = 1.05 g concentration of sample in solution = 82.6 mg/L Dilution factor = 10 I did not carry out specific gravity for this sample and I've used Agilent HPLC I would really appreciate for your help! :-)

2006年5月10日 · Re: Convert mg/L to mcg/ml micrograms and milligrams are weights. There is 1000micrograms in 1 milligram. Liters and milliliters are volumes. There is 1000 milliliters in 1 liter. 20ug/mL is the same as 20mg/L 100mg/L is the same …

2009年6月16日 · Your concentration in mg/L is the same as your grams/m³. To get the grams per second, multiply by the m³/s, to get the weight in an hour multiply by 3600, to get the weight in a day multiply by 24. (If you run continuously). For example, if you have a concentration of 76mg/L urea, and a flow rate of 0.145m³/s, the calculation is

2014年5月5日 · Divide the level in mg/L by 25106 to convert to mmol/L. You will probably need to shift the decimal and prefix as the number will be smaller. Shift decimal three places right for µmol/L, or 6 for nmol/L.

2006年7月11日 · Re: convert Mg/l to ppb I would like know if my laboratory scale can only measure in increments of mg, how to calculate a ppb concentration? For the purposes of calculating the ppb concentration I would like to add 1mg of the contaminant to a fixed quantity of 1m^3 cooling water and would like to know the answer in ppb.

2010年4月25日 · 2460 mg/l of sodium converted to meq/l what is the value If that is just the concentratuion of the sodium ion, divide by 22.99 g/mol = 107 mmol/L (or meq/l for sodium ion, which has charge of +1)

2009年8月27日 · conversion of micromol to mg/l 08-27-2009, 06:41 pm. i have a result silicate in river water 301 micromol ...

2008年1月15日 · Hello- how do I convert a concentration in mg/l to ng/g If it is a dilute water solution, 1 L water weighs very close to 1 kg. Thus x mg/L is approximately x mg/kg 0r 1000*x ng/g.
