Question- A solution of sulfuric acid (H2SO4) is prepared by dissolving sulfuric acid in water. The solution is prepared so that it contains 47% sulfuric acid by mass, which has a specific gravity of 1.34 at 20 °C. What mass, in grams, of sulfuric acid (H2SO4) would be present in 350. mL of this solution? Enter your answer to the ones place (e.g. 12). Do not include units.
Please illustrate work as well as walk me during the problem so that I can follow and understand it.
