Question

a device in your school lab releases gas at a rate of 0.25 liter per second, which means 0.25 of a liter of gas is released every second. the density of the gas is 4.3 grams per liter, which means that there are 4.3 grams of the gas in one liter. set up the calculations to find the number of seconds it will take for the device to release 154 grams of the gas. drag each tile to the correct location. the tiles can be used more than once. 154 g × 4.3 1 0.25 4.3

Explanation:

Step1: Identify the rate - mass and volume relationship

The gas is released at a rate of 0.25 liters per second and has a mass - release rate of 4.3 grams per second. We want to find the time to release 154 grams.

Step2: Set up the proportion

Let $t$ be the time in seconds. We know that the mass - release rate is 4.3 grams per second. So, if the mass $m = 154$ grams, and the rate $r=4.3$ grams/second, we use the formula $m = r\times t$. Then $t=\frac{m}{r}$.

Step3: Calculate the time

Substitute $m = 154$ grams and $r = 4.3$ grams/second into the formula: $t=\frac{154}{4.3}\approx35.81$ seconds.

Answer:

The tiles should be arranged as $\frac{154}{4.3}$ to find the number of seconds it will take for the device to release 154 grams of the gas.
