Analysis
Mass of Carbon | + | Mass of Hydrogen | = | Mass of Sample | |
Sample 1 | 0.862 g | + | 0.138 g | = | 1.0 g |
Sample 2 | 1.335 g | + | 2.214 g | = | 1.549 g |
Sample 3 | 0.852 g | + | 0.136 g | = | 0.988 g |
Yes, the material is a pure compound as all the three samples have the same composition.
