Hydrogen gas is explosive within the range of 4% - 75% v/v. Assuming that each student in your class produces 6 L of H2 and that the lab is not ventilated, is there danger of an explosion.

In order to compute this, we must first take a couple of assumptions of: 1) The laboratory size so we can calculate its volume 2) The number of students working in the lab so we know the total gas produced Let the lab be 11 m × 9 m × 6 m The volume then computes to be: 594 m³ We know that 1 Liter is 1 dm³ 1 m = 10 dm 1 m³ = 1000 dm³ Therefore, the room volume in liters is: 594,000 Liters Let there be 30 students in the laboratory Total gas being produced: 6 × 30 = 180 Liters This works out to be: 0.03% of Hydrogen by volume Therefore, there is no risk of explosion given our assumption of size and students.
