Answer is: True.
Example for p<span>olyhydroxyl alcohol is glycerol.</span>
Glycerol (1,2,3-Propanetriol, glycerine<span> or glycerin) is a simple polyol (it has three hydroxyl group) compound with formula (OH-CH</span>₂-CH(OH)-CH₂OH or C₃H₈O₃).
The glycerine <span>backbone is found in
all lipids known as triglycerides. (ester derived from glycerol and three fatty acids).
Glycerol is soluble in water and it is hygroscopic.</span>
Answer:
0.500 moles
Explanation:
In order to convert grams of any given substance into moles, we need the <em>substance's molar mass</em>:
- Molar Mass of CH₃Br = Molar Mass of C + (Molar Mass of H)*3 + Molar Mass of Br
We can find the molar masses of each element in the periodic table:
- Molar Mass of CH₃Br = 94.94 g/mol
Now we can <em>divide the given mass by the molar mass</em> in order to <u>calculate the number of moles</u>:
- 47.5 g ÷ 94.94 g/mol = 0.500 moles
M1V1 = M2V2
M1 = 0.100 M NaOH
V1 = 14.8 mL NaOH
M2 = ?
V2 = 25.0 mL HCl
(0.100 M)(14.8 mL) = M2(25.0 mL)
M2 = 0.0592 M HCl
