To find the mole ratio of salt to water in a compound, you need to examine the chemical formula of the compound and identify the number of moles of salt and water present.
Let's go through each compound and calculate the mole ratio:
1. Mo(NO3)2.5H2O
In this compound, Mo(NO3)2 represents the salt, and 5H2O represents the water.
To determine the mole ratio, we need to compare the number of moles of Mo(NO3)2 to the moles of water.
The coefficient in front of the formula unit of Mo(NO3)2 is 1, indicating that there is one mole of Mo(NO3)2 present. The coefficient in front of the formula unit of 5H2O is also 1, indicating that there is one mole of 5H2O present.
Therefore, the mole ratio of salt (Mo(NO3)2) to water (H2O) is 1:1.
2. CaSO4.2H2O
In this compound, CaSO4 represents the salt, and 2H2O represents the water.
To determine the mole ratio, we need to compare the number of moles of CaSO4 to the moles of water.
The coefficient in front of the formula unit of CaSO4 is 1, indicating that there is one mole of CaSO4 present. The coefficient in front of the formula unit of 2H2O is also 1, indicating that there is one mole of 2H2O present.
Therefore, the mole ratio of salt (CaSO4) to water (H2O) is 1:1.
3. (CaSO4)2.H2O
In this compound, (CaSO4)2 represents the salt, and H2O represents the water.
To determine the mole ratio, we need to compare the number of moles of (CaSO4)2 to the moles of water.
The coefficient in front of the formula unit of (CaSO4)2 is 1, indicating that there is one mole of (CaSO4)2 present. The coefficient in front of the formula unit of H2O is also 1, indicating that there is one mole of H2O present.
Therefore, the mole ratio of salt [(CaSO4)2] to water (H2O) is 1:1.
In summary, the mole ratio of salt to water for the given compounds is as follows:
- Mo(NO3)2.5H2O: 1:1
- CaSO4.2H2O: 1:1
- (CaSO4)2.H2O: 1:1
