QUESTION: Problem 15P
Calculate each of the following quantities:
(a) Mass in grams of 8.35 mol of copper(I) carbonate
(b) Mass in grams of 4.04 × 1020 molecules of dinitrogen pentaoxide
(c) Number of moles and formula units in 78.9 g of sodium perchlorate
(d) Number of sodium ions, perchlorate ions, Cl atoms, and O atoms in the mass of compound in part (c)
ANSWER:
Solution 15P:
Here, we are going to calculate each of the quantities.
Step 1:
(a) Mass in grams of 8.35 mol of copper(I) carbonate
Here, we have to calculate the mass of 8.35 mol of copper(I) carbonate
The molar mass of copper(I) carbonate (Cu2CO3) = 187.11 g/mol
Given that,
The mol of copper(I) carbonate (Cu2CO3) = 8.35 mol
Therefore,
The mass of copper(I) carbonate (Cu2CO3) = 8.35 mol
= 1562.4 = 1.56
103 g of Cu2CO3
Thus, the The mass of 8.35 moles of copper(I) carbonate (Cu2CO3) is 1.56103 g .
