To calculate the mass of water of hydration lost, you'll need to know the molar mass of water (H₂O). The molar mass of water is approximately 18.02 g/mol.
Given that 0.025 mol of water is lost when heated, we can use this information to calculate the mass of water lost.
Mass of water lost = number of moles of water lost × molar mass of water
Mass of water lost = 0.025 mol × 18.02 g/mol
Mass of water lost = 0.45 g
Therefore, the mass of water lost when the hydrate is heated is 0.45 grams.
To calculate the mass of water lost when a hydrate loses a certain number of moles of water, you need to know the molar mass of water and the number of moles of water lost.
1. Start by calculating the molar mass of water (H2O):
- The molar mass of hydrogen (H) is approximately 1g/mol.
- The molar mass of oxygen (O) is approximately 16g/mol.
- Adding these together gives a molar mass of approximately 18g/mol for water.
2. Next, calculate the mass of water lost by multiplying the molar mass of water by the number of moles lost. In this case, we lost 0.025 mol of water:
- Mass of water lost = 0.025 mol × 18 g/mol = 0.45 g
Therefore, the mass of water lost when this hydrate loses 0.025 mol of water is 0.45 grams.
