Just do 6 x 2.2
6 x 2.2 = 13.2
Answer: B. CH₂OH
Explanation:
First off, we need a liquid solvent. Eliminate C and D.
Now, we have to consider polarity.
- Carbon tetrachloride is nonpolar, so sodium chloride will be insoluble.
- CH₂OH is polar, so sodium chloride will be soluble.
Answer:
Valence Electrons
Explanation:
Valence electrons are the electrons in the outermost shell and can be used to form bonds.
<span>Brass, which is made by melting copper and zinc together, is harder, stronger, morecorrosion resistant and has an attractive gold colour. It still keeps its anti-bacterial properties, which makes it a great material for door knobs, handrails and plumbing fittings. Copper has been used to make coins for centuries.</span>
Answer:
the mass of the glycerine needed in the given solution is 23.92 g
Explanation:
Given;
molarity of the solution (C₃H₈O₃), C = 2.60 M
Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M
The molarity of a solution is given as follows;

The molecular mass of the given solution;
molecular mass = (12 x 3) + (8 x 1) + (16 x 3)
molecular mass = 92 g/mol
The mass of the glycerine needed in the given solution is calculated as follows;
reacting mass = amount of solute (moles) x molecular mass (g/mol)
reacting mass = 0.26 x 92
reacting mass = 23.92 g
Therefore, the mass of the glycerine needed in the given solution is 23.92 g
