Mol% or weight%? Weight percent seems more likely; let's assume that and see what we come up with. We'll assume 100g of the substance to make the numbers pretty; in that case we have: * 34.9 g Na / 23.0 g/mol Na = 1.52 mol Na * 16.4 g B / 10.8 g/mol B = 1.52 mol B (so far the weight percent is looking like a good assumption) * 48.6 g O / 16.0 g/mol O = 3.04 mol O (looking like a greatassumption) Converting that to small whole number ratios, we get an Na:B:O ratio of 1:1:2, so the empirical formula is NaBO2.
how thick are you pouring? i will assume 900 sq. was just width by length. need to multiply by thickness inches to give cubic feet needed. divide that number by 27. this should be yards of concrete needed. my guess little over 4.4 cubes. don't forget to factor humidity. na

Well, let's take a look at this happy little math problem. A factor is a number that can be multiplied to get another number. In this case, 6 divided by 42 leaves a remainder, so 42 is not a factor of 6. Just remember, there are no mistakes in math, just happy little accidents!
UN/NA 1090 and Guide number 127
UN/NA 1203 Guide Number 128
The UN NA number for chlorine is 1017, and the guide number is 124.
UN/NA number 1075 or 1978, guide number 115
The UN number for Chlorine is UN1017, and the guide number is 124.
Nitrogen UN NA number 1065 guide number 121
nitrogen, UN/NA number 1066, guide number 121

The United Nations (UN) number for propane is 1978, and the North America (NA) or DOT guide number is 101. This classification is used for transportation and safety purposes to identify propane gas.
To determine the UN or NA number for motor oil, it is necessary to know its:Flash pointViscosity, andToxicology ratingsin order to determine whether it is subject to regulation at all, and if so in what hazard class. Once that is known, an appropriate generic proper shipping name can be selected and with it, the UN or NA number.
The UN number for nitrogen is UN1066.
