C12H22O11 that the chemical compound for sugar
Answer:
0.4mol/L
Explanation:
Data obtained from the question include:
Number of mole of NaOH(solute) = 0.20 mole
Volume of solution = 0.50 L
Molarity =.?
Molarity is simply mole of solute per unit litre of a solution. This can represented mathematically as:
Molarity = mole of solute /Volume of solution
Molarity of NaOH = 0.2mol/0.5L
Molarity of NaOH = 0.4mol/L
Answer:
you're very beautiful! don't say bad stuff about yourself you look very pretty and you should know that! :)
Explanation:
remember to stay positive about yourself as well :P
Answer:
See below.
Explanation:
1. The water here is the solvent, and the 'sugar and fruit specific chemicals' are considered the solute. That is as the solute is the component dissolved in the solvent.
2. The collision theory states that the greater the collisions, the greater the rate of reaction. When powdered sugar is placed in the water (solvent) it occupies more surface area, resulting in more collisions that speed up the rate of reaction, compared to a cube of sugar - that occupies less surface area. Therefore, the powdered sugar dissolved faster.
3. Molarity describes the number of moles of a substance per unit of volume. The standard unit of volume is liter, giving you the standard units (mol/l). Molality describes the number of moles per unit of mass, typically kilograms (mol/kg).
The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent for molality, and moles of solute dissolved in liters of solvent for molarity. Molality is generally used for concentration.
