Question

Part B: Now perform the calculations you set up in part A Round your answer to the nearest whole number It will take _ seconds for the device to release 154 grams of the gas

Answer 1

Step 01: To write the relation, begin using the relation for seconds.

`(1s)/(0.25L)`

Step 02: To eliminate L, use the other relation, putting the liters in the numerator:

`(1L)/(4.3g)\cdot(1s)/(0.25L)`

Step 03: Multiply everything by 154g.

`154g\cdot(1L)/(4.3g)\cdot(1s)/(0.25L)`

Step 04: Multiply the numerators and the denominators.

`(154g\cdot1L\cdot1s)/(1\cdot4.3g\cdot0.25L)`

Step 05: Multiply the numbers and simplify the units that are in the numerator and in the denominator.

`\begin{gathered} (154\cdot1\cdot1g\cdot L\cdot s)/(1\cdot4.3\cdot0.25\cdot g\cdot L) \\ (154s)/(1.075) \\ =143.3s \end{gathered}`

Answer: It will take 143.3 seconds.
