specific gravity = relative density ( relative to water) , so if the mineral is 10 times the density of water, then its specific gravity is 10
Super Extra Gravity was created on 2005-10-14.
Weight = mass times gravity. On Earth, use 9.82 (or round it to 9.8, or to 10) for gravity.14 (kg) x 10 (Newton/kg) = 140 Newton.
Gravity doesn't have speed , it has acceleration. On Earth gravitational acceleration is 9.8 ms^-2. Often approximated to 10 ms^-2
Gravity is a force. The unit of force is a Newton. F = m x a (Newton's Second Law) = 6 kg x 10 m/s2 (Acceleration due to gravity is 9.8 m/s2 but 10 when rounded) = 60 N
10 ppm = 10/1,000,000 =0.001/100 = 0.001%
10 ppm = 10/1,000,000 = 1/100,000 = 1/100,000*100% = 0.001%
10 ppm mole multiply by molecular weight of water then divided by sample density
10 ppm as a fraction is 10 / 1 000 000 = 0.00001, as a percentage = (10 / 1 000 000) * 100 = 0.001 %
10 g is 10,000 mg and in 1 liter that would be 10,000 ppm. You need to have a volume in order to express the mass as ppm. In other words, 10 g NaCl cannot be expressed as parts per million unless you have the volume that it is in. If it's in a liter, then you will have 10,000 ppm.
ppm means mg per litre. mg/l means 100ug/dl. Therefore there are 10 x 10 micrograms per decilitre in ppm. In other words, 10ug/dl is 0.1 ppm.
From 10 000 BC till 1860, the pre-Industrial Age, the carbon dioxide in air was approximately 278 ppm (0.0278%). In 1900 it was 295 ppm. In 1960 it was 315 ppm. In 1980 it was 335 ppm. In 1990 it was 350 ppm. In 2000 it was 369 ppm. In 2010 it was 388 ppm. In 2011 it was 392 ppm. (March 2011)
Depends on the printer and the settings, but usually around 1 ppm on best quality, about 5 ppm on normal quality, and about 10 ppm on draft quality. Laser printers, on the other hand, range from ~10 to ~100 PPM.
The lel of alcohol is 3.3% - 10% lel - 3300 ppm idlh 15000 ppm
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
A percentage is 'parts per hundred' and there are possibly 100 of them. ppm is parts per million. There are 10 000 hundreds in a million. So multiply your percentage by 10 000. i.e. 3% x 10 000 = 30 000 ppm. but check my math.
You prepare a primary solution then dilute portion of your solution down to the required concentration. For example, you want a 10 ppm salt solution (10 mg/L), you dilute 1 g of salt in 1 L of water you get 1000 ppm salt solution. You take 10 ml of your salt solution (0.01 g salt in 10 g) and add in additional 980 ml of water then you get a 10 ppm weight solution.
