Calculate the weight percent of water in NiSO4 6H2O, how to calculate it?
see your post above.
To calculate the weight percent of water in NiSO4 6H2O, you need to consider the molecular weight of water and the total molecular weight of the compound NiSO4 6H2O.
Step 1: Calculate the molecular weight of water (H2O):
The molecular weight of hydrogen (H) is approximately 1 gram/mol, while the molecular weight of oxygen (O) is approximately 16 grams/mol. Since water consists of two hydrogen atoms and one oxygen atom, the molecular weight of water is:
(2 * 1 gram/mol) + (1 * 16 grams/mol) = 18 grams/mol.
Step 2: Calculate the molecular weight of NiSO4 6H2O:
The molecular weight of nickel (Ni) is approximately 58.69 grams/mol, the molecular weight of sulfur (S) is approximately 32.06 grams/mol, the molecular weight of oxygen (O) is approximately 16 grams/mol, and the molecular weight of water (H2O) is 18 grams/mol. Since there are six water molecules in NiSO4 6H2O, the total molecular weight is:
(58.69 grams/mol for Ni) + (32.06 grams/mol for S) + (4 * 16 grams/mol for O) + (6 * 18 grams/mol for H2O) = 262.36 grams/mol.
Step 3: Calculate the weight percent of water:
Now you can calculate the weight percent of water in NiSO4 6H2O by using the following formula:
Weight percent of water = (Molecular weight of water / Molecular weight of NiSO4 6H2O) * 100.
Plugging in the values:
Weight percent of water = (18 grams/mol / 262.36 grams/mol) * 100.
Weight percent of water ≈ 6.86%.
Therefore, the weight percent of water in NiSO4 6H2O is approximately 6.86%.
