Table 1 shows the heights of 5 sunflower seedlings grown under identical greenhouse conditions for 14 days.
| Seedling | Height () |
|---|---|
| Seedling 1 | 12 |
| Seedling 2 | 15 |
| Seedling 3 | 18 |
| Seedling 4 | 15 |
| Seedling 5 | 20 |

An agricultural scientist measured the water absorption capacity of three different types of superabsorbent polymer gels (Gel A, Gel B, and Gel C) used in soil conditioning. Six trials were conducted for each gel type, and the mass of water absorbed (in grams per gram of gel) was recorded in the table below:
| Gel Type | Trial 1 (g) | Trial 2 (g) | Trial 3 (g) | Trial 4 (g) | Trial 5 (g) | Trial 6 (g) |
|---|---|---|---|---|---|---|
| Gel A | 42.1 | 44.5 | 41.8 | 43.2 | 45.0 | 42.6 |
| Gel B | 51.5 | 48.2 | 53.4 | 49.8 | 50.6 | 52.1 |
| Gel C | 33.7 | 35.2 | 34.0 | 32.9 | 36.1 | 34.5 |
Based on the table, what is the median water absorption capacity, in grams, for Gel B across the 6 trials?
