Yes u can average density on y ais and % (M/m) on Xaxis First need to do a caliberation curve and from that the value of unknown can be determined
| % (M/m) | Density (g/ml) |
| 5 | 1.1315 |
| 10 | 1.119 |
| 15 | 1.1715 |
| 25 | 1.255 |
| 30 | 1.264 |
| 50 | 1.293 |
The Caliberation plot has been made the % (m/m) can be determined for 1.2543 g/ml
From the graph the value will be around 31%
