What is 4.8 gas purity?
The purity of gas is an indication of the amount of other gases it contains. A high purity refers to a low amount of other gases. Gases of higher purity are considered to be of better quality and are usually more expensive. The purity of gas can be expressed as a percentage value or as a decimal fraction. The decimal fraction is an abbreviation of the percentage value, where the first digit represents the number of nines in the percentage value and the last digit represents the last digit of the percentage value. For example, a purity of 99.97% can be abbreviated as purity 3.7 and a purity of 99.9999% is the same as purity 6.0. Source: http://en.wikipedia.org/wiki/Purity_(gas) So 4.8 = 99.998%
What grade is 50 out of 59?
50 out of 59 is 85%.
If you have a 52 percent in science and the exam is worth 30 percent how much do you need to pass to get 50 and over?
If 50 is passing: right now the contribution towards the total grade is (.70)*52, so the total grade = (.70)*52 + (.30)*E [for the final exam grade]. If the target is 50 for the total grade, then 50 = (.70)*52 + (.30)*E, and solve for E = (50 - (.70)*52)/(.30) = 45.3333, so a grade of 46 would put the final grade over 50. By the way, the maximum possible grade of a 100 on the final will result in 66.4 for the total grade.

What is the difference between Analytically pure and chemically pure grades?
Chemical pure grade materials have purity that is suitable for use in general applications. Analytical pure materials have purity that is suitable for use in analytical applications (very sensitive).
what is the unit of purity of a chemical sustance?
If you are referring to chemical purity by grade, I suggest you research the following terms: ACS Grade (American Chemical Society) - highest level of purity Reagent grade - Almost as stringent as ACS USP Grade - Equivalent to ACS for many drugs NF Grade (National Formulary) - Equivalent to ACS for many drugs Laboratory Grade Purified Grade Technical Grade
Is polymer grade ethylene same as the polyethylene?
No, it's not the same thing. Ethylene is a gas used to produce polyethylene (solid). "Polymer grade" is just a purity label for ethylene gas, means that this ethylene is pure enough to be used in polyethylene (or other polymer) production.
