To find the number of moles in 98.3 grams of aluminum hydroxide (Al(OH)₃), first calculate its molar mass. The molar mass of Al(OH)₃ is approximately 78.00 g/mol (26.98 g/mol for Al + 3 × 16.00 g/mol for O + 3 × 1.01 g/mol for H). Using the formula ( \text{moles} = \frac{\text{mass}}{\text{molar mass}} ), we have ( \text{moles} = \frac{98.3 , \text{g}}{78.00 , \text{g/mol}} \approx 1.26 , \text{moles} ). So, there are approximately 1.26 moles of aluminum hydroxide in 98.3 grams.
