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 , we need to use the molar mass of .The molar mass of is 98.1 g/mol.To calculate the number of grams, we multiply the number of moles by the molar mass:Number of grams = Number of moles × Molar massNumber of grams = 6.50 moles × 98.1 g/molNumber of grams = 638.65 gTherefore, the correct answer is A. 638g.
