Answer:
Distillation is an important commercial process that is used in the purification of a large variety of materials. However, before we begin a discussion of distillation, it would probably be beneficial to define the terms that describe the process and related properties. ... Elevation of the boiling point with an increase in external pressure, while important in cooking and sterilizing food or utensils, is less important in distillation.

Answer:
C) 0.75 mol.
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in 1.0 L of the solution.
So, The molar concentration of sucrose in a can of soda is 0.375 M means that: every 1.0 L of sucrose contains 0.375 mol of sucrose.
∴ 2 liter bottle of soda of the same concentration contains (2 * 0.375 mol = 0.75 mol) of sucrose.
<em>Thus, the right choice is: C) 0.75 mol.</em>
Answer:
Cobalt chloride= D cobalt(111) chloride
Answer:
3.88%
Explanation:
Given parameters:
Grams of solute = 3.55g of NaCl
Grams of solution = 91.55g of solution
Mass percentage
of NaCl(%) = grams of solute/grams of solution x 100
Mass percent = 3.55/91.55 x 100
Mass percent = 3.88%
Sorry i don’t know the answer i just wanted to inform you that, that persons link is fake.
