325 ml of Helium gas is heated from 25.0 C to 32.3o C. what is the new volume of He?

Please show your work and express it in a scientific notation also.

Answer:
Volume 1 / Temperature 1 = Volume 2 / Temperature 2

but u have to change the celcius to Kelvin. (25 + 273 = 298 , 32.3 + 273 = 305.3)

325 / 298 = X / 305.3

cross multiply:

(325)(305.3) = 298 X

divide by 298 on both sides:

X = 332.9 --> 333 (3 sig figs) --> 3.33 x 10^ -2 mL (dont forget units)
