Question

A device in your school lab releases gas at a rate of , which means 0.25 of a liter of gas is released every second. The density of the gas is , which means that there are 4.3 grams of the gas in one liter. Set up the calculation to find the number of seconds it will take for the device to release 154 grams of the gas. What is the formula to solve

Answer 1

To find the time required to release 154 grams of gas, multiply the gas density by the release rate to get grams per second, then divide the total grams by this rate.

Step-by-step explanation:

To set up the calculation for the number of seconds it will take for the device to release 154 grams of the gas, we need to utilize the given rate of gas release and its density.

First, let's find out how many grams are released per second using the gas's density. Since the gas has a density of 4.3 grams per liter and the device releases 0.25 liters every second, the amount of gas released per second is:

4.3 grams/L × 0.25 L/s = 1.075 grams/s.

Now, to find the total time taken to release 154 grams of the gas, we divide the total mass by the mass released per second:

154 grams ÷ 1.075 grams/s = approximately 143.26 seconds.

Therefore, it will take approximately 143.26 seconds for the device to release 154 grams of the gas.
