What is the formula mass for $Al_2(C_2O_4)_3$?
54+72+192=318 $Al_2=54$ $C_2=24 and then 24*3=72$ $O_4=64 and then 64*3=192$

What s the covalent compound formula for oxalic acid?
$"Oxalic acid"$ is the simplest dicarboxylic acid, $HO(O=)C-C(=O)OH$; its salts are called $"oxalates"$, i.e. $C_2O_4^(2-)$, which is a chelating ligand. In the laboratory it is often used as the $"dihydrate"$,...

I need some help understanding how some ions have the same electronic arrangement as noble gasses? Like why does a Li+ ion has the same electron structure as helium or a Mg2+ ion has the same electron structure
as a Na+ ion and an O2- ion?
A completely filled outer electron shell is stable because it can not gain any more electrons, it is full. Being completely full it has no desire to lose electrons thereby...

How do you balance this equation: $Fe_2(C_2O_4)_3 -> FeC_2O_4 + CO_2$?
So we approach the equation by the method of half equations: $Fe(III)$ is reduced to $Fe(II)$: $Fe^(3+) + e^(-)rarrFe^(2+)$ $(i)$ And $"oxalate ion"$ is oxidized to $CO_2$: $C_2O_4^(2-) rarr 2CO_2...

Oxalic acid is 26.68% carbon, 2.24% hydrogen, and the remainder oxygen, what is its empirical formula?
Assume 100 g of acid. Breaking it down into its components, there are $(26.68*g)/(12.01 *g*mol^-1*C); (2.24*g)/(1.00794 *g *mol^-1*H); (71.08*g)/(16.00*g*mol^(-1)*O)$ $=$ $C:H:O$ $=$ $2.22:2.22:4.44$ $=$ $1:1:2$. Therefore, empirical formula of oxalic...

10.00 ml of 0.1089 M oxalic acid neutralises 18.65 ml of sodium hydroxide solution. What is the concentration of the sodium hydroxide ?
$sf(H_2C_2O_(4(aq))+2NaOH_((aq))rarrNa_2C_2O_(4(aq))+2H_2O_((l)))$ $sf(n_(H_2C_2O_4)=cxxv=0.1089xx10.00/1000=0.001089)$ $:.$$sf(n_(NaOH)=0.001089xx2=0.002178)$ $sf(c=n/v)$ $:.$$sf([NaOH]-=(0.002178)/(0.01865)=0.1168color(white)(x)"mol/l")$

A solution contains 0.063 g of oxalic acid, $H_2C_2O_4 * 2H_2O$, in 250 mL. What is the molarity of this solution?
$"Molarity"$ $=$ $"Moles of solute"/"Volume of solution"$ $=$ $(0.063*g)/(126.07*g*mol^-1)xx1/(0.250*L)$ $=$ $??*mol*L^-1$

How does the $"normality"$ of an $"oxalic acid"$ solution relate to its $"molarity"$?
Oxalic acid is a diacid, i.e. $HO(O=)C-C(=O)OH$. Formally each equiv of acid requires 2 equiv of base to achieve neutrality. Of course $pK_(a2)$ will be substantially greater than $pK_(a1)$. You...

If you had 325 grams of a 5.0% by mass solution of citric acid, how many grams would be the acid and how many grams would be water? How many moles of citric acid would it contain?
$"mass percent"="grams of solute"/"grams of solution"xx100"$ The mass in grams of a mass % solution, is the sum of the mass in grams of the and the mass in grams...

Oxalic acid, $H_2C_2O_4$, occurs as the potassium or calcium salt in many plants, including rhubarb and spinach. An aqueous solution of oxalic acid is 0.585 molal $H_2C_2O_4$. The density of the solution is 1.022 g/mL. What is the molar concentration?
The first thing that you need to do here is to pick a sample of this solution and use its to determine how many moles of it contains. To...
