What is the mass of 0.513 mol Al2O3? Give your
answer to the correct number of significant
figures. (Molar mass of Al2O3 = 102.0 g/mol)
0.513 mol Al2O3 = |
g Al2O3

52.3

Explanation:

52.3

Explanation:

You would need to take the given number of moles and multiply by the molar mass, so

0.513 mol Al2O3 (102.0g Al2O3/1 mol Al2O3) = 52.326

Since you're only given 3 sig figs, you report your answer with 3 sig figs.

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
