1.08 g/cm^3
(when multiplying or dividing you use the least amount of significant figures to answer your question by which is the 19.5. That gives you 3 significant figures.)

4.83 km
(when adding or subtracting however you use the least precise the 4.810 goes into the thousandths place which is more precise then the 0.08 which only goes to the hundredths place.)

A balloon is filled with a gas and has a volume of 1.79 L at 2.82 atm pressure. What will its volume be if

Black_prince [1.1K]

Answer:

<h2>The answer is 0.95 L</h2>

Explanation:

In order to find the volume when the pressure is changed to 5.30 atm we use Boyle's law which is

$P_1V_1 = P_2V_2 \\$

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the final volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question

P1 = 2.82 atm

V1 = 1.79 L

P2 = 5.30 atm

So we have

$V_2 = \frac{2.82 \times 1.79}{5.3} \\ = 0.9524150943...$

We have the final answer as

Hope this helps you
