What is the molarity of 0.1g HCl in 0.3litres

Accepted Answer

To calculate the molarity, we need to follow these steps:
1. Calculate the moles of HCl:
- Molar mass of HCl = 1.01 g/mol (H) + 35.45 g/mol (Cl) = 36.46 g/mol
- Moles of HCl = (0.1 g) / (36.46 g/mol) = 0.00274 mol
2. Calculate the molarity:
- Molarity (M) = Moles of solute / Volume of solution (in liters)
- Molarity = (0.00274 mol) / (0.3 L) = 0.00913 M
Therefore, the molarity of 0.1g HCl in 0.3 liters is approximately 0.00913 M.
