Problem 93P
Calculate each of the following quantities:
(a) Moles of compound in 0.588 g of ammonium bromide
(b) Number of potassium ions in 88.5 g of potassium nitrate
(c) Mass in grams of 5.85 mol of glycerol (C3H8O3)
(d) Volume of 2.85 mol of chloroform (CHC13;d = 1.48 g/mL)
(e) Number of sodium ions in 2.11 mol of sodium carbonate
(f) Number of atoms in 25.0 μg of cadmium
(g) Number of atoms in 0.0015 mol of fluorine gas
ANSWER:
Solution 93P:
Step 1: (a)
Here, we have to calculate the moles of compound in 0.588 g of ammonium bromide.
Given that,
The mass of = 0.588 g
The molar mass of = 97.94 g/mol
Therefore,
The moles of = (0.588 g
)
= 0.006 mol
Thus, the moles of compound in 0.588 g of ammonium bromide is 0.006 mol.
