0.5 micro gram = 0.5 x 1000 = 500 nano grams. Hence 779.4 nano grams is greater than 0.5 micro grams by 279.4 nano grams

How many grams are equal to 65000 mcg?
.65 grams. Move the decimal over 3 places to the left.
How many nanograms of THC to fail an army drug test?
The DoD uses a screening test that will confirm your use of THC if your urine contains over 50 nanograms per milliliter of urine. If you test negative you pass, the test goes no further. If you test positive via this screening test your urine is then sent thru a mass spectrometer which will confirm your use of THC if your urine contains more than 15 nanograms of THC.
Human blood contains about 1.34 micrograms of iron per deciliter how many grams of iron are in 1.00ml of human blood?
13.4 micrograms. Deci- meaning 1/10th of a liter. Just move your decimal point over 1.
Is a nurse is to administer 240 micrograms and has 200 micrograms per mililiter how many miligrmas should be?
You will have over a millilitre for a start. If you administer 1ml, you administer 200ug. 240-200ug is 40ug still needed. 40/200 is 1 fifth or 0.2 of a millilitre. Therefore 1+0.2 is 1.2ml needed to be administered.
Is it true that during a drug test THC can be present but not enough to fail?
Your body does in fact create THC but a low percentage, therefore yes but there is a limit - i believe your nanogram count cant be over 25 nanograms
How much iodine is an overdose?
On average (and each person is slightly different) anything over 1,100 micrograms, total, can be considered an overdose. This includes the iodine that you get from food. 1,100 micrograms is the same as 1.1 milligrams. A full gram of water, say, occupies a volume about the same as a sugar cube. So it takes very, very little pure iodine in you to be an overdose. Yet, you cannot live normally without a tiny bit of iodine in your body. That is why table salt comes with a tiny amount of iodine in it.
Is it true that Joey Jordison the drummer from slipknot once took 72 tabs of acid at one time at a party?
I'm not sure if it is true or not, but it's a possibility. It takes over a hundred hits of pretty good acid to OD. The lethal dose level is 12,000 micrograms and today's good street hits normally range from 75- 150 micrograms.
What is a normal PSA level for a man age 70?
PSA levels that are considered normal for men are in the range of four to nine nanograms per millimeter in blood. Anything over these numbers indicates a possibility of prostate cancer.
How do you convert Milligrams per liter to moles per liter?
In order to convert between milligrams and micromoles, one has to know the molar mass of the substance in question, then simply convert from grams to moles. As an example, let's assume that the measurement is that of oxygen, or O2, and that there's 10 milligrams per liter. First, divide by 1,000, to convert to grams, in this case, .01 grams. Then, divide this amount by the molar mass, which represents the number of grams in a mole. For O2, this is approximately 31.9988. This gives us a result of around .0003125 moles, or 3.125 x 10^-4. Then, we multiply by 1,000,000 to convert from moles to micromoles. The end result is approximately 312.5 micromoles in the liter.
Does tobacco contain arsenic?
In minute quantities (approx.10-30 micrograms/kg in tobacco smoke), far too small to do any -- noticeable harm when compared to the other ingredients. And far too little to do any noticeable harm when compared to the levels of arsenic in the food we eat, the water we drink and the 'fresh air' breathe. The smoke from one cigarette MAY contain UP TO 30 nanograms (billionths of a gram) of arsenic. The maximum level of arsenic allowed in drinking water is 10 parts per billion. So half a litre of water (500grams) may contain 5,000 nanograms of arsenic, equivalent to that from over 150 cigarettes or more, and still be considered 'safe'. The maximum level of arsenic in food, such as bacon and eggs, is 500 parts per billion. A 'safe' egg weighing approximately 60 grams may contain up to 30,000 nanograms of arsenic - 1,000 cigarettes-worth. P.S. Historically, some tobacco may have contained signficantly greater concentrations of arsenic. (Tobacco Control are not particular concerning the source of their 'facts'.) The insecticide lead arsenate was widely used, not only on tobacco but also on other crops, such as apples and cranberries. Its use was banned in the 1980s.
How do you convert the micromole per liter into microgram per ml?
The formula is no. moles is mass over molecular mass. If you multiply micromole by molecular mass you get micrograms. Then you have to divide by 1000 to convert per litre to per millilitre.
Number of chromosomes in E. coli?
E.coli genome constist of a SINGLE circular chromosome containing 4.6 Mb i.e. 4.6 X 10^6 bases. The weight of one base is 330 daltons and 1 Dalton is equal to 1.661^-24g. there fore the CHROMOSOMAL WEIGHT (in micrograms) is 660 X 1.661 X 10^-18 X 4.6 X 10^6 which is equal to 5.043 X 10^-9 MICROGRAMS.
