What is the original mass of 12.5 mg after 3 half lives?
After 3 half-lives, the remaining mass is ( \frac{1}{8} ) of the original mass. So if the original mass is 12.5 mg, the final mass after 3 half-lives would be ( 12.5 , \text{mg} \times \frac{1}{8} = 1.56 , \text{mg} ).
What is the equation for finding distance lifted when force and mass are given?
The equation for finding distance lifted when force and mass are given is: distance lifted = (force * distance)/ mass * gravity, where force is the applied force, mass is the mass of the object being lifted, distance is the vertical distance lifted, and gravity is the acceleration due to gravity (9.81 m/s^2).
There are 1000 mg in every gram If something has a mass of 458 mg what is the mass expressed in grams?
The mass of the object would be 0.458 grams. This is calculated by dividing the mass in milligrams (458 mg) by the conversion factor (1000 mg per gram).
What is the atomic mass of magnesium Mg?
Mg: 24.305 K: 39.0983
How do you convert cc in mg?
To convert cc (cubic centimeters) to mg (milligrams), you need to know the density of the substance in question. Once you have the density, you can multiply the volume in cc by the density to get the mass in mg. The formula for the conversion is: mass (mg) = volume (cc) x density (mg/cc).
How do you get 900 mg converted to grams?
Divide mg by 1,000 to get the same mass in grams. 1,000 mg = 1 gram 900 mg = 0.9 gram
The half-life of strontium-90 is 28 years How long will it take a 76 mg sample to decay to a mass of 19 mg?
56 years
How many mg are in 90 pounds?
90 lbs = 40,823,313.3 mg
What equals 900 milligrams equals how many grams?
900 mg = 0.9 g900 mg = 0.9 g900 mg = 0.9 g900 mg = 0.9 g900 mg = 0.9 g900 mg = 0.9 g
How many grams does 900 mg equal?
1000 mg = 1 gram so 900 mg = 900/100 g = 0.9 g. Simple!
What is the mass of 1200 mg?
At the surface of the earth, mass = weight, so 1200 mg weight = 1200 mg mass
What is 90 mg in Ml?
Milligrams can't be converted to milliliters. Milligrams measure mass, while milliliters measure volume.
What is the recommended dosage of grape skin?
Red grape skin extract capsules: 200 - 600 mg at 30 % anthocyanins.
The half-life of strontium-90 is 28 years. How long will it take a 76 mg sample to decay to a mass of 19 mg?
After 28 years your sample halves, ie becomes 38 mg. In another 28 years it will have halved again to 19 mg, so your answer is 56 yearsIt may not seem important, but you should remember that your sample is not evaporating. The actual 76 mg sample will still have almost all of its mass after 56 years. But by that time only 19 mg of it will be strontium-90. The rest of the sample will still be there, but it will have become Zirconium-90 which is stable.And thank your teacher for giving you an easy number to work with. The actual half-life is closer to 28.8 years.
How many milligrams in 90 kilograms?
90 kg = 90 million mg
How many mls is 90 grams?
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
What is the original mass of 12.5 mg after 3 half lives?
After 3 half-lives, the remaining mass is ( \frac{1}{8} ) of the original mass. So if the original mass is 12.5 mg, the final mass after 3 half-lives would be ( 12.5 , \text{mg} \times \frac{1}{8} = 1.56 , \text{mg} ).
