Calculate the molarity of a solution made by adding 35.0 mL of concentrated perchloric acid (70.5 % by mass, density 1.67 g/mL)

to some water in a volumetric flask, then adding water to the mark to make exactly 2000 mL of solution. (It is important to add concentrated acid or base to water, rather than the other way, to minimize splashing and maximize safety.)

Molarity is equal to the number of moles of solute per liter solution.

number of moles solute: (molar mass of perchloric acid is 100.45 g/mol)
35.0 mL * (<span>1.67 g/mL) *0.705 * (mol/100.45 g) = 0.41 moles
liter solution = 2000 ml * (1 L/1000 ml) = 2 L

molarity is equal to 0.41 moles/ 2 L  =0.205 M</span>

Of the following statements about water's latent heat and changes in state, which is/are true? choose all that apply.
postnew [5]

When water evaporates, its latent heat of evaporation absorbs heat.

<h3>What is Latent heat?</h3>

A body or thermodynamic system can release or absorb latent heat during a constant-temperature process, often a first-order phase transition.

There are two types of latent heat:

  1. The heat of freezing
  2. The heat of vaporization

The statements about water's latent heat and changes in state are:

  • The heat of freezing is the quantity of thermal energy produced as a liquid freezes, and the heat of vaporization is the quantity of thermal energy needed to change a liquid into a gas.
  • Water may move energy from one location to other thanks to latent heat.
  • There aren't any weak (hydrogen) bonds between water molecules in the vapor state.
  • Hurricanes are propelled by the latent heat of condensation, which occurs when water vapor condenses and turns into a liquid.
  • All water molecules in the solid state are connected by flimsy (hydrogen) bonds.
