The mass fraction of sodium chloride is 0.0625
<h3>What is the mass fraction of sodium chloride in the solution?</h3>
The mass fraction of sodium chloride is the ratio of the mass of sodium chloride to the total mass of the solution.
The mass fraction of sodium chloride is determined as follows;
mass of sodium chloride = 20 g
- mass of water = volume * density
density of water = 1 g/mL
volume of water = 300 mL
mass of water = 300 mL * 1 g/mL
mass of water = 300 g
total mass of solution = 20 + 300 = 320 g
mass fraction of sodium chloride = 20/320
mass fraction of sodium chloride = 0.0625

Albinism is a recessive trait.
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
