What is analar grade?
It is a way of defining the standard of purity of a chemical compound
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 letter grade is 42 of 50?
A
What is the difference between different grade gas?
The purity is different.
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
What is the purity difference between hydrogen peroxide AR grade and hydrogen peroxide LR grade?
Hydrogen peroxide AR (Analytical Reagent) grade is of higher purity compared to LR (Laboratory Reagent) grade. AR grade typically has a purity of 95-97%, while LR grade has a purity of around 70%, making AR grade more suitable for analytical and research applications where higher purity is required.
What purity is research grade Hydrogen?
Research grade Hydrogen typically has a purity of 99.999% or higher. This level of purity ensures that the hydrogen is suitable for use in various laboratory and research applications where high-quality results are necessary.
How much does an arisenic cost per gram?
Prices for arsenic can vary greatly depending on the grade and purity of the material. In general, industrial-grade arsenic can range from $1-$10 per gram, while higher-purity laboratory-grade arsenic can be more expensive, ranging from $50-$100 per gram or more.
Is polymer grade ethylene same as the polyethylene?
No, polymer grade ethylene refers to the high-purity ethylene used as a raw material in polymer production, while polyethylene is a polymer formed from the polymerization of ethylene molecules. Polymer grade ethylene is the starting material to produce polyethylene through polymerization processes.
What is the purity of street cocaine?
50%
What is a pure sustance for science grade 7?
99,99999 % purity
What purity level is required for medical grade oxygen?
95%
What instrument measures the purity of Argon gas?
An argon gas analyzer measures the purity of Argon gas. The analyzer can be used to determine the actual content of Argon gas in a specific sample.
What is the difference between technical grade and commercial grade chemicals?
Technical grade chemicals are typically higher in purity and are used in laboratory settings for research and analysis. Commercial grade chemicals, on the other hand, are more commonly used in industrial applications and may have slightly lower purity levels but are still suitable for their intended purpose.
What is LR or AR grade chemicals?
LR (Laboratory Reagent) grade chemicals are of a lower purity level compared to AR (Analytical Reagent) grade chemicals. LR grade chemicals are commonly used in general laboratory procedures when high purity is not critical, while AR grade chemicals are of a higher purity and are used for analytical testing where accuracy is important.
