Agas sample has a density of 1.17 g/l. what volume of this gas will havea mass of 2.25 mg?

Answer : The volume of the gas sample is 0.00192 L.

Explanation :

The density of a substance is defined as the mass per unit volume.

The formula for density can be written as

Step 1 : Convert mass from mg to g.

The density of the sample is given as 1.17 g/L

The mass of the sample is 2.25 mg.

Since density has the unit "g", we need to convert the mass from mg to g.

The conversion factor for g to mg is , 1 g = 1000 mg.

Step 2 : Use density formula.

The density formula can be rearranged to solve for volume as follows.

Mass = 0.00225 g

Density = 1.17 g/L

Let us plug in these values in the above formula.

The volume of the gas sample is 0.00192 L or 1.92 mL

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
