79470.2mL
Explanation:
Given:
Volume = 21gallons
problem, convert to milliliters;
gallons to milliliters
1 liter = 1.057 quarts
1 gallon = 4 quarts
we can simply solve this by establishing and using a conversion factor of 1 ;
1 gallon = 4 quarts
1.057 quarts = 1 liter
0.001L = 1mL
21gallons x 
= 79470.2mL
we say;
From;
1gallon = 3784.2mL

It is reduced by nascent hydrogen to the secondary alcohol C6H5.CH.OH.CH3 phenyl-methyl-carbinol, and on oxidation forms benzoic acid.
Answer:
The answer is given below
Explanation:
When electronegativity difference arises between the bonded atoms, then a molecule is polar.
When electros are shared equally between the bonded atoms or when the polar bonds in a bigger molecule cancels out each other, then a a molucule is non polar.
(a) 50% isopropanol/H2O,--- 2 (second least polar)
(b) 25% isopropanol/H2O,----- 3 (third least polar)
(c) pure water----- is 4 (most polar)
(d) 70% isopropanol/H2O. 1 (least polar)
