The table below shows the concentration of different components in the blood plasma and in the filtrate within the Bowman's capsule of a healthy adult.
| Component | Concentration in the blood plasma | Concentration in the filtrate |
|---|---|---|
| Glucose | 0.9 mg per cm3 | 0.9 mg per cm3 |
| Albumin (protein) | 40.0 g per dm3 | 0.0 g per dm3 |
| Red blood cells | 5.2 × 106 per cm3 | 0.0 per cm3 |
| Platelets | 2.5 × 105 per cm3 | 0.0 per cm3 |
Calculate the difference between the number of red blood cells and the number of platelets in 1 cm3 of blood plasma.
