To calculate the mass of a 26.2 mL sample of sulfuric acid, you need to know the density of sulfuric acid. The density of sulfuric acid is 1.84 g/mL. So, the mass of a 26.2 mL sample of sulfuric acid is:

$$mass = density * volume$$

$$mass = 1.84 g/mL * 26.2 mL$$

$$mass = 48.288 g$$

Therefore, the mass of a 26.2 mL sample of sulfuric acid is 48.288 g.
