0.05g of x per 100cm3 what is this parts per million?
Question:
Answers:
50mg in 100ml = 500mg/l
This is equivalent to 500ppm
Let me explain, so that some of your other replies can grasp. This is a weight/volume situation. 1000mg in 1g and 1,000,000mg within 1 kg; since 1 litre contains 1000ml and each ml is nominally 1 gramme, next to 1000g in a kilo, the unit can be changed. Yes we do have to assume that the litre is equivalent to the kilogramme, but that's the make-up of it.
Now, 0.050g is 50mg and 100ml is 1/10 of 1 litre - convert to litres and you have 500mg per litre or 500mg per 1,000,000mg
hence the parts per million.
You must trust this concept 100% as it works!
500 ppm.Verify from
50000
trick grill you have neither molarity or the molecular mass of x You can individual get as far as that you know you enjoy 500mg/l but to go from Volume of a solution to the parts per million, you own to know MM, Molarity, or number of Moles of "x" in the substance, otherwise, adjectives you have is that you could own one 50mg particle and 100ml of sea, in which the ppm is close nil, or you have trillions of particle that add up to 50mg and transport up a large volume of space contained by which x occupies and massively little water. Given this information, it is impossible to convey
0.5g per 1000cm^3
500parts(g) per 1000 000(million)
Your units are adjectives ambiguous.
There cannot be a ratio between a mass and a volume unless the density(ies) is/are known.
Also, do you want the ratio of loads or the ratio of volumes?
Also, is it (100 cm) cubed? (a cubic meter)
or 100 (cubic centimeters)?
Sorry about one picky, picky, picky.
Assuming the density of water (1 gr/cc) for your 0.05 grams, and you want the volume ratio, and you designed 100 cc; it is:
(1,000,000/100) * 0.05 = 500 ppm
