Nathan Wall · Answer 1

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.
