The mole fraction of water in 36 gm water and 34 gm NH3 solution is

To find the mole fraction, we first need to find the moles of each component.

Step 1: Find the moles of water (H2O) The molar mass of water is approximately 18 g/mol. So, moles of water = mass/molar mass = 36 g / 18 g/mol = 2 moles

Step 2: Find the moles of NH3 The molar mass of NH3 (Ammonia) is approximately 17 g/mol. So, moles of NH3 = mass/molar mass = 34 g / 17 g/mol = 2 moles

Step 3: Calculate the mole fraction of water The mole fraction is calculated as the moles of the component divided by the total moles of all components. So, mole fraction of water = moles of water / total moles = 2 moles / (2 moles + 2 moles) = 2/4 = 0.5

So, the mole fraction of water in the solution is 0.5.
