The number of seconds it will take is 143.25 seconds.The formula is s=g/1.075

Step-by-step explanation:

Given that the rate of gas release is 0.25 liter every second.This means;

1 second= 0.25 liter released

Also;

4.3 grams of gas equals 1 liter

This means;

4.3 grams = 1 liter

So for 154 grams, find the number of liters

=154/4.3= 35.81 liters

But you know;

0.25 liters = 1 second

35.81 liters=?

Cross multiply

(35.81*1)/0.25 =143.25 seconds

Let g be the grams of the gas, and l be the liters of the gas, then to get l you divide g by 4.3. This given you the formula;

l=g/4.3

Let s be the seconds it take for a gas device to release l liters of gas, so to get s you divide l by 0.25. This will be;

s=l/0.25 = (g/4.3) / 0.25

This simplifies to;

s= g/(4.3*0.25)

s=g/1.075
