Table 1. Summary of the Straight-Chain Alkanes
Name Formula Number of Structural Isomers
Octadecane C18H38
Nonadecane C19H40
Eicosane C20H42 366,319 (!)

Answer:
0.034 mol (4dp)
Explanation:
Use the formula n = m/M where n= number of moles, m=mass in grams and M=molar mass in g/mol.
Therefore to find how many moles, divide the mass in grams (2) by the molar mass of sodium chloride which is 22.99+35.45
Compare them accordingly with the formula of E=hc/wavelength
Answer:
The percentage of volume of ethanol is 35%.
<u>Explanation:</u>
The percentage of volume of ethanol is calculated by
Percent of volume of ethanol = (volume of X / total volume) * 100
We are going to assume these volumes will be added together to make 100mL.
Percent volume of Ethanol = (volume of ethanol / total volume) * 100
= 35mL / 100mL * 100
= 35%
