A gas has a volume of 490. mL at a temperature of -35.0 degrees C. What volume would the gas occupy at 42.0 degrees Celsius? Please show work.

648.5 mL

Explanation:

Here we will assume that the pressure of the gas is constant, since it is not given or specified.

Therefore, we can use Charle's law, which states that:

"For an ideal gas kept at constant pressure, the volume of the gas is proportional to its absolute temperature"

Mathematically:

where

V is the volume of the gas

T is its absolute temperature

The equation can be rewritten as

where in this problem we have:

is the initial volume of the gas

is the initial temperature

is the final temperature

Solving for V2, we find the final volume of the gas:

indium, and thallium have three electrons i think
