Question

Given the following fictitious combination of fictitious elements a, b, and c, calculate the molar mass 3.78 of the compound a(bc3)2 given the following atomic mass values

Option 1: 25 g/mol
Option 2: 62 g/mol
Option 3: 36 g/mol
Option 4: 92 g/mol

Answer 1

To calculate the molar mass of the compound a(bc3)2, we need to find the molar mass of each element in the compound and then multiply it by the number of atoms of that element in the compound. Given the atomic mass values, the molar mass of a(bc3)2 is 340 g/mol.

Step-by-step explanation:

To calculate the molar mass of the compound a(bc3)2, we need to find the molar mass of each element in the compound and then multiply it by the number of atoms of that element in the compound. Given the atomic mass values, the molar mass of a is 25 g/mol, the molar mass of b is 62 g/mol, and the molar mass of c is 36 g/mol. Now, we can calculate the molar mass of the compound a(bc3)2:

First, let's calculate the molar mass of bc3. b has a molar mass of 62 g/mol, while c has a molar mass of 36 g/mol. As there are 3 c atoms in bc3, the molar mass of bc3 is:

(62 g/mol) + (3 * 36 g/mol) = 170 g/mol

Next, we can calculate the molar mass of a(bc3)2. Since there are 2 bc3 units in a(bc3)2, the molar mass of a(bc3)2 is:

2 * 170 g/mol = 340 g/mol
