QUESTION:
Calculate each of the following quantities:
(a) Mass in grams of \(0.68 \mathrm{~mol}\) of \(\mathrm{KMnO}_{4}\)
(b) Moles of \(\mathrm{O}\) atoms in \(8.18 \mathrm{~g}\) of \(\mathrm{Ba}\left(\mathrm{NO}_{3}\right)_{2}\)
(c) Number of \(\mathrm{O}\) atoms in \(7.3 \times 10^{-3} \mathrm{~g}\) of \(\mathrm{CaSO}_{4} \cdot 2 \mathrm{H}_{2} \mathrm{O}\)
ANSWER:
Step 1 of 4
(a) Mass in grams of 0.68 mol of \(\mathrm{KMnO}_{4}\)
Here, we have to calculate the mass in g of 0.68 mol of \mathrm{KMnO}_{4}
We know that,
The molar mass of \(\mathrm{KMnO}_{4}\) = 158.034 g/mol
