What is the mass of 7.346 moles of CaOH2?
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
How many moles of OH ions are produced from the hydroxides of group ii metals for every mole of the base that dissociates?
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
How much is 2 scientific moles?
Two moles is equivalent to 12,044281714.10e23 molecules, atoms or ions.
What is the number of moles of Cl ions combine completely with 0.25 molesof Mg 2 ions is?
20.4
How much moles of OH liberate during the borax hydrolysis?
B4O7^2- + 7H2O = 4H3BO3 + 2OH- B4O7^2- : 2OH- = 1:2 Therefore there are twice the number of moles of Hydroxide ions produced as there are Borate ions
What is the mass of 7.346 moles of CaOH2?
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
How many sodium ions are in 2 moles of NaCl?
2
How many moles of ions are produced when 2 mol of Na2CO3 dissociate?
Na2CO32 * 2 = 4 moles sodium.===========================
How many moles of Cl- ions are needed to completely combine with 0.25 moles of Mg 2 ions?
Mg2+ + 2 Cl- are in 1 : 2 ratio (of ions) so also 0.25 : 0.50 mole ratio
How many moles of ammonium ions are in 4.50 mol NH4 2CO3?
There are 9 moles of NH4 (Ammonium ions) in Ammonium carbonate. There are 2 moles of NH4 per molecule and 4.5 molecules, so 2 moles times 4.5 is 9 moles.
How many moles of Cl ions are needed to completely combine with 0.25 moles of Mg 2 ions?
Balanced equation first.Mg + Cl2 -> MgCl2All is one to one, so,0.25 moles of chlorine ions are needed here.================================
If 2 moles of sodium sulfate are dissolved in water how many moles of ions are in solution a- 2 b- 3 c- 6 d- 15?

How many chloride ions are in a sample of salt that contains 2 moles of MgCl2?
2.4088 x 1024 chloride ions
How many chloride ions are in a sample of salt that contains 2 moles of KCl?
1.20442 x 1024 chloride ions
How many moles of ions are produced by the dissociation of 1 mole NH4Br?
I assume that is 28.0 grams.28.0 grams MgCl2 (1 mole MgCl2/95.21 grams)= 0.294 moles magnesium chloride==========================Now,One mole Mg 2+ = 0.294 moles Mg 2+ ions=============================2 moles Cl - = 0.588 moles Cl - ions=========================
How many moles of OH ions are produced from the hydroxides of group ii metals for every mole of the base that dissociates?
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
How many nitrate ions are in a sample of salt that contains 2 moles of Ca NO3 2 4H2O?
2.4088 x 1024 nitrate ions
