1. Find the molar mass of HNO3:
* H: 1.01 g/mol
* N: 14.01 g/mol
* O: 16.00 g/mol (and there are three oxygen atoms)
Molar mass of HNO3 = 1.01 + 14.01 + (16.00 x 3) = 63.02 g/mol
2. Use the conversion factor:
* 1 mole HNO3 = 63.02 grams HNO3
3. Calculate the mass:
* 2.6 moles HNO3 * (63.02 grams HNO3 / 1 mole HNO3) = 163.85 grams HNO3
Therefore, there are approximately 163.85 grams of HNO3 in 2.6 moles of the compound.
