3. A helium filled balloon has a volume of 39.0mL at 17C and the current atmospheric pressure is reading 802mmHg on the barometer. What volume will the helium gas take up when the pressure reading on the barometer drops to 637mmHg and the temperature plummets to 7C?

.0466 L

Explanation:

To start off, use dimensional analysis to convert everything to standard PV=nRT units.

x = .039 L

x = 1.055 atm

17 +273 = 290

...and so on.

Solve for n for the starting pressure, volume and temp. You'll need it for the final equation.

n= PV/RT = .0017 number of moles

Solve for volume of the end point.

V= nRT/P = .0466 L of helium, or 46.6ml Less pressure means it will take up more space.

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
