A teaspoon of dry coffee crystals dissolves when mixed in a cup of hot water. This process produces a coffee solution. Which term best identifies how the original crystals are classified? -Reactant
-product
-solvent
-a solute

The correct answer is - solute.

Explanation:

A solute is one half of a solution that is dissolved in the other half of the solution, known as the solvent. Solute particles are always less or lower in quantity or concentration than the solvent in a solution.

In this case, coffee crystals are dissolved in hot water so the solute will be coffee crystals and the amount of coffee crystals are also less than the amount of solvent.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
