How many grams are in 6.50 moles of H_(2)SO_(4) A. 638g B. 98.1 g C. 15.1 g D. 0.0663 g A B C D

To find the number of grams in 6.50 moles of $H_{2}SO_{4}$, we need to use the molar mass of $H_{2}SO_{4}$.<br /><br />The molar mass of $H_{2}SO_{4}$ is 98.1 g/mol.<br /><br />To calculate the number of grams, we multiply the number of moles by the molar mass:<br /><br />Number of grams = Number of moles × Molar mass<br />Number of grams = 6.50 moles × 98.1 g/mol<br />Number of grams = 638.65 g<br /><br />Therefore, the correct answer is A. 638g.
