QUESTION:
Calculate each of the following quantities:
(a) Mass in grams of \(8.42 \mathrm{~mol}\) of chromium(III) sulfate decahydrate
(b) Mass in grams of \(1.83 \times 10^{24}\) molecules of dichlorine heptaoxide
(c) Number of moles and formula units in \(6.2 \mathrm{~g}\) of lithium sulfate
(d) Number of lithium ions, sulfate ions, \(\mathrm{S}\) atoms, and \(\mathrm{O}\) atoms in the mass of compound in part (c)
ANSWER:Step 1 of 5
(a) Mass in grams of \(8.42 \mathrm{~mol}\) of chromium(III) sulfate decahydrate
Here, we have to calculate the mass of \(8.42 \mathrm{~mol}\) of chromium(III) sulfate decahydrate
The molar mass of chromium(III) sulfate decahydrate,
\(\mathrm{Cr}_{2}\left(\mathrm{SO}_{4}\right)_{3} \cdot 10 \mathrm{H}_{2} \mathrm{O}=572.4 \mathrm{~g} / \mathrm{mol}\)
