No, it is not. When the prefix changes, you know it's the decimal places or the amount of zeroes that changes, and not the figure itself. i.e. the first significant figure in each is 1 and 5 respectively, so this cannot be correct. 100 micrograms is actually 0.1 and not 0.5 milligrams.
To find out how many ounces of chemical it would take to make 100 gallons of finished dilution at 0.5%, we can set up a proportion. Since 11 ounces of chemical are used in 10 gallons of water, we can establish the ratio of ounces of chemical to gallons of water as 11:10. By setting up a proportion and solving for x, we find that it would take 110 ounces of chemical to make 100 gallons of finished dilution at 0.5%.
0.000025 move the decimal pt by 5 places to the left because it is e to the power negative 5.

DefinitionBlood lead level is a test that measures the amount of lead in the blood.Alternative NamesBlood lead levelsHow the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.How to prepare for the testNo special preparation is needed.If your child is to have this test performed, it may be helpful to explain how the test will feel, and even demonstrate on a doll. Explain the reason for the test. Knowing the "how and why" may reduce the anxiety your child feels.How the test will feelWhen the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThis test is used to screen people at risk for lead poisoning, including industrial workers and children who live in urban areas. It is also used to see if treatment for lead poisoning is working.While lead serves no function in our bodies, it is usually found in the body in some amount since it is so common in the environment. Low levels in adults are not thought to be harmful, but in infants and children, low levels of lead can lead to toxicity that may cause deficits in intellectual or cognitive development.See: Lead poisoningNormal ValuesAdults:Less than 20 micrograms/dL of lead in the bloodChildren:Less than 10 micrograms/dL of lead in the bloodNote: dL = deciliterNormal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAdults who have been exposed to lead should have blood lead levels below 40 micrograms/dL. Treatment is recommended if you have symptoms of lead poisoning, or if your blood lead level is greater than 60 micrograms/dL.In children, a blood lead level greater than 10 micrograms/dL requires further testing and monitoring. The source of lead must be found and removed. A lead level greater than 45 micrograms/dL in a child's blood usually indicates the need for treatment.What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)ReferencesWoolf AD, Goldman R, Bellinger DC.

1 milligram = 1000 micrograms so 5.0 milligrams = 5000 micrograms. Simple!
1 mg = 1000 micrograms (ug) Now you need to cross multiply and cancel units to get your answer.
1 milligram = 1000 micrograms0.5 milligram = 500 microgramsThere are 1,000 micrograms (mcg) per milligram.So, 0.5mg = 0.5 x 1,000 = 500mcg
50,000mg 1 gram = 1000 milligrams
0.000 05 kilo equals 50 milligrams. (= 1/20 000 of a kilogram)
.05% can be written as .05/100 for Percent is 1/100 of a number.. so .05/100 = .05/100 x 100/100 = 5/10000 or .0005 therefore.. .05% of something is .0005 of something..
05 is an integer. An equivalent fraction is 5/1
05 grams is 5 times larger than 1mg. If you meant 0.05, this is 20 times less.
.05 = 5/100
Put .05/1 move decimal places all the way right to whole numbers 5/100 factor out a five 1/20 ------------------the fractional equivalent of 0.05
0.00110231pound mass equals to 500 milligrams
100 multiplied by 0.05 is five.
