How do I find the moles of Fe in a .2M solution of Fe(NO3)3?
Moles of Fe can be calculated by Multiplying Molarity with Volume of SOlution(inL)
Lets suppose you have 2L solution of 0.2M Fe(NO3)3
Then moles of Fe = 2*0.2 = 0.4 moles Fe
How many moles Fe of are there in 100.0 g of Fe(NO3)3.9H2O (MW = 404.0)? Express your answer to 2 decimal places Do not include units How many grams of Fe of are there in 100.0 g of FeCl2.4H2O (MW = 198.81)? Express your answer to 2 decimal places Do not include units
I have 1.01 of a solution that is 0.100M Fe(NO3)2 and 0.200M Cu(NO3)2. I want to seperate the metal ions. I gradually add a solution that is 0.100M in K3PO4, 0.100 M in KOH, and 0.100 M in K2CO3.What volume of the solution do I need to add to get the first metal to begin to precipitate?
How do I calculate the Initial Fe(NO3)3 for each tria. Please help and show all work Please!!!! 1 2 3 4 5 mL Fe(NO3)3 1.0 2.0 3.0 4.0 5.0 0.0003 M mL KSCN 1.0 M 5 5 5 5 5 mL HNO3 0.1 M 4 3 2 1 0 Total mL 10 10 10 10 10 Initial [Fe(NO3)3] 3.0x10^-5 Absorbance .284 1.085 1.325 1.820 2.121 Transmittance 52.01 8.22 4.73 1.51 0.76
If NH3 (ammonia, pKb=4.74) is added to a solution of Fe(NO3)3 such that right after the addition we have 50 mL of 5.0 M NH3 and 0.0040 M Fe(NO3)3 (right after addition) Find Kc for Fe2+(aq) + 2OH-(aq) ---> Fe(OH)2 (s) any type of explanation would be helpful please!

Why is HNO3 added to the Fe(NO3)3 solution used in chemical equilibrium experiment? How does the HNO3 accomplish its function?
How many moles of chloride ions are there in 100 mL of a 2M solution of HCl?
You will be preparing a standard solution by mixing 2 solutions: 0.200 M Fe(NO3)3 and 0.00200 M KSCN. The concentration of the M Fe(NO3)3 solution is 100 times greater than the concentration of KSCN solution. What is the purpose of using a large concentration of Fe(NO3)3 and a small concentration of KSCN to make the standard solution? EXPLAIN
am confused how to start this. for my lab i obtained 24ml of 0.000075M Fe(NO3)3, 40ml of 1M KSCN and 45ml 0f 0.1M HNO3. i was asked to pipet different volumes into 12 testubes. testtube 1....4.00ml Fe(NO3)3, 3.00ml KSCN and 1.00ml HNO3. Calculate the molarity of the complex [Fe(SCN)]^2+ that was present at equilibrium. Am confusing my ideas please help
15. The pH of a solution of ferric nitrate, Fe(NO3)3, is not 7.00. This fact is best explained by the equation: A) NO3-(aq) + H2O(1) + HNO3(aq) + OH(aq) B) Fe3+(aq) + 6 H2O(1) Fe(OH)3(aq) + 3 H30+(aq) C) [Fe(OH2)6]3+(aq) + H20(1) 3 H3O+(aq) + [Fe(OH2)5(OH)]2+(aq) D) H3O+(aq) + OH-(aq) + 2 H2O(1) E) HNO3(aq) + H2O() H30+(aq) + NO3-(aq)
