The answer is 0,625 moles.
4000 meters = 4 kilometers.
To convert ppm to wt%, you need to divide ppm with 1000000 to get to wt%.For example:If you have 4000ppm, it is the same as 0.004 wt%.I dont agree with this answere.Actually 4000ppm means 4000mg in 1Kg (1000g). Hence a simple solution is as under;1000g contains 4000mgor1000g contain 4 gm. Hence 100g will contains 0.4 grams. This is the answere i.e. 0.4%because % means amount present in 100 grams.The first answer above should be:To convert ppm to wt% (percent by weight), you need to divide ppm by 10,000.For example:If you have 4000 ppm, it is the same as 0.4 wt%.If a lab result for the concentration of lead (Pb) in a paint chip sample is 10,400 ppm, the concentration in percent lead by weight is 1.04. If the result is reported as 1.04 % Pb by weight, then the concentration can be converted to 10,400 ppm.
50/4000 = 0.0125 = 1.25%
4000 kilometers = 400 000 000 centimeters
100cm = 1meter therefore 4000 cm = 40meter
4 g in 1 liter will give you a 4000 ppm solution.
If you know how to multiply and divide, the solution is easy. Divide 4000 by 100 and you get the answer of 40. If you look at the number of zeroes, you know that the answer must have one zero, as 4000 has three zeroes, and 100 only has two.
2016/4000 = 0.504
4000mL contains 400cL* There are 10mL per cL and 0.1cL per mL
1 tablespoon contains 15 ml.. 4 grams is 4000 milligrams.. 4000 mg in 600 ml ??? mg in 15 ml ( 4000 mg * 15 ml ) / 600 ml = 100 mg.
4000% of 4000 =4000/100 * 4000 =160,000
