1. There is no code abbreviation Mo in the monetary unit. I checked the list of country names and monetary units and found no such monetary unit, only MK (Kwacha, Malawi) and MRO (ujiya, Mauritania),
are you wrong. In addition, according to the International Monetary Fund, money supply can be classified. There is M0, which means cash.

The "crown character" on the RMB banknote is two or three letters printed on the banknote to mark the printing batch, which is arranged and printed by the banknote printing factory according to certain rules“ "Number" refers to the Arabic numeral serial number printed on the back of the prefix, which is used to indicate the order of each banknote in the batch with the same prefix

the prefix is printed in front of the serial number of the coin, which is used to count the special number of the printing batch. The prefix of the same batch of banknotes is the same. A group of Arabic numerals are arranged after the crown to indicate the printing order of each note. There are letters, Roman numerals, native characters and so on

and the third set of RMB uses Roman crowns, which means that when collecting the third set of RMB, you often hear or see two or three crowns. In fact, they are the same as two crowns and three crowns

two crowns and three crowns are the initial appellations of the fourth set of RMB notes. Before the serial numbers on the front, bottom, left or right of the fourth set of RMB notes, there are two crowns with the Pinyin of AQ, DH and ZJ, and three crowns with Hai, BGC and D2c. Before the four sets of notes, they were called track 2, track VIII, track II x, track III, track IV x, track v v II, and they were called two Rome or three Rome

Weight percentage, wt%

wt% = (mass of B / mass of a + mass of B) × Calculation method of 100%

weight percentage and concentration:

C (mol / L) = [1000ml] ×ρ( g/㎝ˆ- 3) ×ω%]／ Molar mass of solution (g / mol) × 1 l solution = 1000 ρω％/ M

C: concentration of solution, unit: mol / L

ω％： Mass fraction of the mass in the solution, ω％= Solute mass / solution mass × 100％

ρ： Density of solution in g / cm-710- 3

weight percentage = quantity / total mass of the material × 100％

extended data:

volume concentration

(1) molar concentration the concentration of a solution is expressed by the number of moles of solute contained in 1 liter of solution, which is called molar concentration, expressed by the symbol mol / L. for example, if 18.4 moles of sulfuric acid are contained in 1 liter of concentrated sulfuric acid, the concentration is 18.4 mol

molarity (molgl) = molarity of solute / volume of solution (L)

(2) equivalent concentration (n)

the concentration of solution is expressed by the gram equivalent of solute contained in 1 liter of solution, which is called equivalent concentration, expressed by the symbol n

for example, if 1 liter of concentrated hydrochloric acid contains 12.0 grams of equivalent hydrochloric acid (HCl), the concentration is 12.0 n

equivalent concentration = gram equivalent number of solute / solution volume (L)

mass volume concentration

the concentration expressed by the mass number of solute contained in unit volume (1 m3 or 1 L) of solution is called mass volume concentration, expressed by the symbol g / m or mg / L. For example, if the mass of hexavalent chromium in 1 liter chromium containing wastewater is 2 mg, the concentration of hexavalent chromium is 2 mg / L (mg / L)

Wt%: weight percentage

wt% formula:

wt% = (mass of B / mass of a + mass of B) × Calculation method of 100%

< H2 > extended data

weight percentage and concentration:

C (mol / L) = [1000ml] ×ρ( g/㎝ˆ- 3) ×ω%]／ Molar mass of solution (g / mol) × 1 l solution = 1000 ρω％/ M

each letter indicates the meaning:

C: concentration of solution, unit: mol / L

C ω％： Mass fraction of the mass in the solution, ω％= Solute mass / solution mass × 100％

ρ： Density of solution in g / cm-710- 3

weight percentage = amount of material / total mass × 100％

7. Wt originally refers to the mass percentage of alloy, written as wt%. As a short for what on the Internet.
