Problem 15P 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)

Step-by-Step Solution:
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 = 1.56103 g of Cu2CO3

Thus, the The mass of 8.35 moles of copper(I) carbonate (Cu2CO3) is 1.56103 g .

Step 2:

(b) Mass in grams of 4.04 × 1020 molecules of dinitrogen pentoxide

Here, we have to calculate the mass of 4.04 × 1020 molecules of dinitrogen pentoxide.

Given that,

The number of molecules =4.04 × 1020 molecules

The molar mass of N2O5 =108.02 g/mol

We know that

1.0 mole of =

Therefore, the moles of  = 4.04 × 1020 molecules

= 6.708710–4 mol of

Therefore,

The mass of   = 6.708710–4 mol of

= 0.072467 g

= 0.0725 g

Thus, the  mass of 4.04 × 1020 molecules of dinitrogen pentoxide is 0.0725 g .
