mole ratio of (CaSO4)2.H2O
What about it?
To determine the mole ratio of a compound, you need to know the chemical formula of the compound. In this case, the compound is (CaSO4)2.H2O, also known as calcium sulfate dihydrate.
The chemical formula indicates the number and types of atoms present in the compound. It consists of three elements: calcium (Ca), sulfur (S), and oxygen (O) along with two water molecules (H2O).
To determine the mole ratio, you need to count the number of moles of each element present. Let's break down the compound and calculate the mole ratio step by step:
(CaSO4)2.H2O can be separated into two parts: CaSO4 and H2O.
1. Calculate the mole ratio of CaSO4:
- Calcium (Ca) is present once in the formula.
- Sulfur (S) is also present once.
- Oxygen (O) is made up of four atoms in the sulfate ion (SO4^2-).
Thus, the mole ratio of CaSO4 is 1:1:4 (Ca:S:O).
2. Calculate the mole ratio of H2O:
Since there are two molecules of water (H2O), it means there are two moles of hydrogen (H) and two moles of oxygen (O).
Therefore, the mole ratio of H2O is 2:2 or 1:1 (H:O).
Combining the mole ratios obtained from CaSO4 and H2O, we can conclude that the overall mole ratio of (CaSO4)2.H2O is:
1:1:4:2 (Ca:S:O:H).
In summary, the mole ratio of (CaSO4)2.H2O is 1:1:4:2 for calcium, sulfur, oxygen, and hydrogen, respectively.
