Dr. Bob

ok well here is what i have gotten so far: on the problem

H2O: 1.118 mol
C2O4: .58681 mol
Fe 3+: .2025 mol
K^+: .3862 mol

That is what ive gotten doing 20.14 g(1 mol / 18 g) = 1.118 mol
and so on with the rest of them

Did i do that wrong

I answered this below but repost your new work here.

Based on the information you provided, it seems like you are trying to determine the number of moles for each substance based on their given mass. Let's go through each calculation to see if you did it correctly.

For H2O:
You started with a mass of 20.14 g and used the molar mass of water (H2O), which is 18 g/mol, in your calculation.
So, 20.14 g × (1 mol / 18 g) = 1.118 mol.
Your calculation for H2O is correct.

For C2O4:
You mentioned that you obtained 0.58681 mol of C2O4, but you didn't provide the initial mass used in the calculation. If you have the mass of C2O4, you can divide it by the molar mass of C2O4 (which is the sum of the atomic masses of each element in the compound) to find the number of moles.

For Fe3+:
Similarly, you mentioned that you obtained 0.2025 mol of Fe3+, but you didn't provide the initial mass used in the calculation. If you have the mass of Fe3+, you can divide it by the molar mass of Fe3+ to find the number of moles.

For K+:
Again, you mentioned that you obtained 0.3862 mol of K+, but you didn't provide the initial mass used in the calculation. If you have the mass of K+, you can divide it by the molar mass of K+ to find the number of moles.

To summarize, you provided the correct calculation for H2O but didn't provide the necessary information for C2O4, Fe3+, and K+. To determine if you did those calculations correctly, we need the mass values you used.
