A gas, while expanding under isobaric conditions, does 660 J of work. The pressure of the gas is 1.40 x 105 Pa, and its initial volume is 1.70 x 10-3 m3. What is the final volume of the gas?

Would I multiply the two values?

W = p*dV = p(Vf - Vi)--for isbaric p is constant.
Plug in values of W,p and Vi to find Vf

So I set this up as 660=1.40e^5(1.70e^-3 - Vf)

Then to solve for Vf I multiplied 1.70e^-3 and 1.40e^5 and then divided by 660. Did I do this correctly?
