3. Discuss the difference between molarity and molality, state the units of each, state the symbol for each, and give an example
dangina [55]

<span>Molality(m) or molal concentration is a measure of concentration and it refers to amount of substance in a specified amount of mass of the solvent. Used unit for molality is mol/kg which is also sometimes denoted as 1 molal. It is equal to the moles of solute (the substance being dissolved) divided by the kilograms of solvent (the substance used to dissolve).</span>

Molarity(M) or molar concentration is also a measure of concentration and represents the amount of substance per unit volume of solution(number of moles per litre of solution. Used unit for molarity is mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar (1 M).

Molality is preferred when the temperature of the solution varies, because it does not depend on temperature, (neither number of moles of solute nor mass of solvent will be affected by changes of temperature), while molarity changes as temperature changes(volume of solution changes as temperature changes).

Please Help! I just started balancing equations and my teacher gave me this. Thanks in advance! :D
Alenkasestr [34]
So you need to put numbers before each compound to make sure there are the exact same number of elements on each side. If you put a 4 before NH4 there are 4 Nitrogen and now 16 hydrogen. I just played around with numbers and guessed until I got them even.

Dioxane, C4H8O2, has an enthalpy of fusion of 145.8 J g–1 and its melting point temperature is 11.0 °C. How much heat is require
kumpel [21]

Answer:

20703.6J

Explanation:

Quantity of heat (Q) = mass of dioxane × enthalpy of fusion

Mass of dioxane = 142g

Enthalpy of fusion of dioxane = 145.8J/g

Q = 142g × 145.8J/g = 20703.6J
