1000parts per billion = how much gold per to n in grams
ng/g=ppb
its mean
1ppb= 10000000
10ng=10ppb
100ng= 100ppb
This is 2 nanograms/litre.
29.1
Divide by 1000.
There are 1,000,000,000 micrograms in a kilogram. This actually means parts per billion. Parts per million would be mg/kg. So to get here, you need to divide by 1000.
Nickel is an element. Therefore, in any nickel item it is 1 billion parts per 1 billion or 1 million parts per million.
nanograms per litre is a measure of concentration whereas milligrams is a measure of mass. The two measure different things and it makes no sense to convert from one to the other. If it helps, though, 1 milligram = 1 million nanograms.
Parts Per Billion - 2014 is rated/received certificates of: USA:R
1000 ppm = 1 ppb I think equation to convert ppm to ppb is: 1 ppm = 1000 ppb, or 1 ppb = 1/1000 ppm * * * * * Wrong way around, I am afraid. 1000 parts per billion is 1 ppm. To convert ppb to ppm divide by 1000.
50ppb is equal to 0.05ppm

about 0.003 parts per billion in the earth's crust.
The question, as stated, cannot be answered sensibly. A naongram per microlitre is a measure of density, with dimensions [ML-3]. A nanogram [alone] is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
