.513mol x (102g/1mol)

Essentially, this is .513 x 102
Which equals: 52.326
But because you can only have 3 significant figures, your answer is:
52.3 grams

I hope this Helps!

Answer : The mass of 0.513 mole Al_2O_3 is, 52.3 grams

Solution : Given,

Moles of Al_2O_3 = 0.513 mole

Molar mass of Al_2O_3 = 102.0 g/mole

Formula used :

\text{Moles of }Al_2O_3=\frac{\text{Mass of }Al_2O_3}{\text{Molar mass of }Al_2O_3}

Now put all the given values in this formula, we get the mass of Al_2O_3

0.513mole=\frac{\text{Mass of }Al_2O_3}{102.0g/mole}

\text{Mass of }Al_2O_3=52.3g

Therefore, the mass of 0.513 mole Al_2O_3 is, 52.3 grams
