Work Step by Step
In the first sample of H2SO4, hydrogen is present at a ratio of 2.02 g : 32.07 g : 64.00 g for sulfur and oxygen respectively. Therefore, for every gram of hydrogen present, there are 32.07/2.02 = 15.87 g of sulfur and 64.00/2.02 = 31.68 g of oxygen. To find the number of grams of sulfur and oxygen present in the second sample of H2SO4, we can use this ratio and multiply it by the number of grams of hydrogen present in the second sample.
So, if a second sample of H2SO4 contains 7.27 g of hydrogen, the number of grams of sulfur would be 7.27 * 15.87 = 116.36 g and the number of grams of oxygen would be 7.27 * 31.68 = 231.63 g.
