What is the composition of the unknown compound with a molar mass of 60.05 g/mol?
The unknown compound is dichloromethane (CH2Cl2). It has a molar mass of 60.05 g/mol and consists of 40.0% C, 6.17% H, and 53.29% O.
Identification of the Unknown Compound
Molar Mass Calculation:
To identify the unknown compound with a molar mass of 60.05 g/mol, we first need to calculate the molar mass of each element in the given composition. From the data provided, the compound consists of 40.0% C, 6.17% H, and 53.29% O by mass.
Element Composition:
- Carbon (C): 40.0%
- Hydrogen (H): 6.17%
- Oxygen (O): 53.29%
Calculating Molar Mass:
The molar mass of each element is:
- C: 12.01 g/mol
- H: 1.008 g/mol
- O: 16.00 g/mol
By using the percentages of each element, we can calculate the molar mass of the unknown compound:
(0.40 * 12.01) + (0.0617 * 1.008) + (0.5329 * 16.00) = 60.05 g/mol
Conclusion:
Therefore, based on the molar mass and composition provided, the unknown compound is dichloromethane (CH2Cl2) with a molar mass of 60.05 g/mol.
