Answer:

322.1262g

Explanation:

This question is mole to mole reaction but the answer should be in gram.

4moles of Al gives 2 moles of Al2O3

3.1581 moles of Al gives x moles of Al2O3

Cross multiply

4x= 3.1581×2

4x=6.3162

X=6.3162/4

X=1.57905moles

To convert to gram

Moles ×molar mass

Molar mass of Al2O3 is 204g

Which means 1.57905×204= 322.1262g

A base has Kb of 2.5 x 10-11. which of the following statements is true?(1 point)
Furkat [3]
I disagree with the answer pick of D. If you have a neutral pH 7 solution and you proceed to add a base even with an relatively insignificantly low Kb your solution would still be more basic then acidic. The answer should be b which is true that the base only ionizes slightly in aqueous solution. This is also truer to the definition of what Kb represents.
