Q. What is the mole fraction of solute in a solution containing 1 mol of NaCl in 9 mol of water?

9 मोल पानी में 1 मोल NaCl वाले घोल में विलेय का मोल अंश क्या है?

A
0.1
B
0.9
C
0.01
D
0.001

Explanation

Given:

  • 1 mol NaCl (solute)
  • 9 mol H₂O (solvent)

Mole fraction of solute = moles of solute / total moles

  • Total moles = 1 + 9 = 10 mol
  • Mole fraction of NaCl = 1 mol ÷ 10 mol = 0.1
