Expert Answer
Specific gravity is the ratio of density of a substance compared to the density of fresh water at 4°C (39° F). At this temperature the density of water is at its greatest value and equal 1 g/mL. Since specific gravity is a ratio, so it has no units.
Sp. gr. = 1.73
= 1.73 g/mL
= 1730 g/L
% weight = 80%
Therefore, 1730 x 0.80 = 1384 g/L of H2S04
MW H2S04 = 98
E.W. = 49
1N H2S04 = 49 g/L
1384 g/L / 49 g/L= 28.24N
