G/l na mol/l

$\begingroup$ Dimensional analysis is helpful. g/L divided by g/mol gives mol/L. $\endgroup$ - user55119 Jun 12 at 18:40 add a comment | 2 Answers 10g NaOH x 1 mol NaOH / 40.0 g NaOH. You cancel out the g NaOH on both sides, and end up with 0.25 mol NaOH. Then, just plug the number of moles into the formula: Molarity = moles / liters. M = 0.25/ 1. M = 0.25 mol/L. Now try the rest on your own It's probably easiest to do this problem with the factor-label method. 0.136 mol/L x 48.5g NaCl/mol = 6.596 g/L. The 48.5 is the approximate molar mass for NaCl (from the periodic table)

Dobrý den,jak bych měla vypočítat tento následující příklad mám hmotnostní koncentraci 10 g/l chlornanu sodného.A mám spočítat látkovou koncentraci která má vyjít 134 mmol/l nebo 0,134 mol/l. Mr(Na)=23 a chloru 35. m(NaCl) = 2 mol/L × 0.1 L × 58 g/mol = 11.6 g. To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g). Therefore. Mol/L is a measure of amount-of-substance concentration.

단위환산. g/L to mmol/L A solution of a valine(Mr 117) contains 2.94 g/L. Calculate its molarity in mmol/L. ----- Mr 117 = 117 g/mol 이므로, valine 2.94 g의 몰수. M = + × = g mol− Use the formula m n M = to convert from mass to moles, and m n M= × to convert from moles to mass. Converting between g L-1 and mol L-1 Think of M as a bridge, with g L-1 at one end and mol L-1 at the other. To get from mass concentration to mol L-1, you need to get to g L-1 first. To convert from g L-1 to mol L-1, divide by Značení. Tato veličina se označuje c.V tomto článku je značka veličiny doplněna indexem označující danou složku směsi. Podle normy se doporučuje uvádět značky pro dané složky směsi v závorkách na stejném řádku, např. c(H 2 SO 4).. Definice =, kde n A je látkové množství složky A a V je celkový objem roztoku.. Jednotky. Hlavní jednotka v soustavě SI je mol m −3 1. You would multiply 1.027x10^-10 mol/L by the molar mass in (g/mol) -> check the units, mols will cancel and you'll have g/L. 2. Then, multiply by 0.1 -> You use 0.1 because 0.1 L = 100 mL. If you are following units, multiplying the g/L you got in the first step by 0.1 L/ 100 mL will leave you with g/100 mL The units are mole per liter. $\mathrm{mol \times L^{-1}}$ is more conveniently written $\mathrm{mol/L}$. This set of units is referred to as molarity, and is a common measure of concentration for a solute dissolved in a solvent.The solute may be a solid (ionic or covalent), a gas or a liquid, but is commonly a solid. The solvent may be a gas or liquid, but is commonly a liquid

concentration - How to convert g/L to mol/L - Chemistry

A gram per litre or gram per liter (g/L or g/l) is a unit of measurement of mass concentration that shows how many grams of a certain substance are present in one litre of a (usually liquid or gaseous) mixture. It is not an SI unit - the SI unit of mass concentration is kilogram per cubic metre, which is equivalent.. Metric prefixes are often applied, giving units like milligrams per litre. How many molar in 1 mol/L? The answer is 1. We assume you are converting between molar and mole/litre. You can view more details on each measurement unit: molar or mol/L The SI derived unit for amount-of-substance concentration is the mole/cubic meter. 1 mole/cubic meter is equal to 0.001 molar, or 0.001 mol/L

The Handbook of Chemistry & Physics gives 100% ethanol as 0.7893 kg/L and 98% as 0.7954 kg/L. Interpolating gives density of mixture as 0.7923 kg/L, of which 99% is ethanol, or 0.7844 kg Re: ng/ml to mol/l Hi, a 1Molar solution would therefore be 182g/L.
