  • Waiting for answer How does vapor pressure related to intermolecular forces?

    Vapor pressure is the amount of gas in equilibrium with the liquid and solid phases. The higher the vapor pressure, the more gas in equilibrium, and thus the easier it is for the substance to vaporize (turn to gas), and vice versa. Intermolecular forces are the attractive interactions between mol...

    313 g of ##LiNO3## is needed. Step 1: Calculate the number of mol of ##Li2SO4## ##(n(Li2SO4))## ##n(Li2SO4)## = mass/molar mass = 250/109.9 = 2.27 mol (3sf) Step 2: Use the ratio from equation to find ##n(LiNO3)## 'What you want over what you got' ##n(LiNO3) = 4/2 X n(Li2SO4)## = 2 X 2.27 = 4.55 m...

  • Waiting for answer What is the definition of osmosis in terms of solute concent...

    is the movement of solvent molecules ( water ) from where they are pure to where they are impure. As we can see in the diagram , if solute concentration is increased , them purity of solvent will decrease hence more solvent molecules will enter into it.
