Answer: (3) ppm

Explanation: Concentration is defined as the amount of solute dissolved in a known amount of the solvent or  a solution.

Parts per million (ppm) is used to express the concentration when a very small quantity of solute is present in a large quantity of the solution. It is defined as the mass of solute present in one milion (10^6) parts by mass of the solution.

ppm=\frac{\text {mass of Solute}}{\text {Mass of solution}}\times 10^6

L/s is used to express flow rate.

J/g is used to express energy per unit mass.

kPa is used to express pressure.

Also to clarify further, L/s is a unit of flow rate, J/g is a unit of energy per unit mass, and kPa is a unit of pressure known as kilo pascals which is equivalent to 1000 pascals

A patient arrives in the emergency with a burn caused by steam. Calculate the heat that released when 17.7 g of steam
MaRussiya [10]

The steam releases 39.9 kJ when it condenses..

The steam condenses and transfers its energy to the skin.

<em>q = m</em>Δ<em>H</em>_cond = 17.7 g × (-2257 J/1 g) = -39 900 kJ = -39.9 kJ

The negative sign shows that the steam is releasing energy
