Why is CoCl2 in Hygrometers?
CoCl2 is used in hygrometers due to its color-changing abilities. It can help calculate the levels of humidity in the air.
How many Co atoms are there in 230 grams of CoCl2?
To answer this question you need the molecular weight of CoCl2. CoCl2 molecular weight is 129.84 g/mole 230g CoCl2 divided by the molecular weight 230 g / 129.84 g/mole = 1.77 moles of CoCl2 Multiply the moles by Avagodro's number 1.77 mole * 6.022 X 1023 molecules/mole = 1.07 X 1024 molecules of CoCl2
Is CoCl2.6H20 a liquid or solid?
CoCl2 6H20 is liquid.
How would you prepare 100.00mL of 0.060M CoCl2 from 0.150M CoCl2?
MV = MV 100 x 0.060 = 0.150 V V = 100 x .06 / .15 = 40.0 ml Measure accurately (burette or pipette) 40 ml of 0.150M CoCl2 then dilute until the total volume is 100.00 ml.
What is the balanced molecular equaton for FeCl3 plus CoCl2?
FeCl2 + CoCl3
When colbalt chloride unties with water to form hexahydrate its formula is written CoCL2 6H2O?
Yes, CoCl2 * 6H2O is the hexahydrate of the an hydrate CoCl2.
What color is CoCl2-6H2O-ethanol?
Dark Blue
How many grams of CoCl2 6H2O must you measure out in a container to have exactly Avogadros number of particles?
Idn!!
Would CoCl2 6H2O cause a chemical reaction?
Cobalt(II) chloride may be a reactant in a chemical reaction.
In the presence of water what happens to anhydrous cobalt chloride?
The colour become initially purple and after (with more humidity) pink.
Whatcolor is change by heat CoCl2-6H2O?
CoCl2 cobaltous chloride, a crystalline compound, is blue when dehydrated and a pale rose color when hydrous. One application is the use of cobaltous chloride in sympathetic ink. When the writing is dried in air it is nearly colorless to do absoption by water in the air. When the ink is warmed it becomes bright blue. All the information above was found on dictionary.die.net/cocl2
What is the coordination number for CaF2?
Coordination Numbers/Geometry Ca CN=8 Cubic coordination F CN=4 Tetrahedral coordination
In geometry is the x on the bottom or the side?
In geometry, the x-coordination is a line that runs vertically from the origin.
What is the percentage of water in the hydrate CoCl2 and 6H2O Show your work?
1. Find the molar mass of the hydrate.Find the molar mass of the water molecules (18.01528 x # water molecules) and of the anhydrate; add the values together to find the molar mass of the hydrate.Molar Mass Water + Molar Mass Anhydrate = Molar Mass Hydrate2. Find the percent of water in hydrate.Divide the molar mass of water by the molar mass of hydrate; multiply by 100%.- Mass waterMass hydrate x 100%
When a sample of 20.0 g of CoCl2 - 6H2O is dried in an oven until dry CoCl2 is obtained what is the mass of dry cobalt chloride?
Equation:CoCl2.6H2O + heat --> CoCl2 + 6H2OYou have the mass of CoCl2.6H2O, which is 20g.You know the Mr of CoCl2.6H2O as well:58.93 + 35.5(2) + 6(18)= 237.93gmol-1 (The 18= H2O)You know the formula to calculate the no. of moles:n=mass/Mr, therefore n= 20/237.933 = 0.0841 molesThe ratio of CoCl2.6H2O: CoCl2 is 1:1, therefore CoCl2 has the same number of moles as does CoCl2.6H2O.So you want the mass of CoCl2? Well you havethe the Mr of it and now you have the no. of moles.Mr of CoCl2:58.93 + 35.5(2)= 129.93 (Or you could simply do 237.93 - 6(18) )Since n=mass/Mr you simply rearrange to get mass by itself. Which is:mass= n x MrTherefore the mass ofCoCl2ismass = 0.0841 x 129.93 = 10.92g (Answer)Daniel Hajsadr
