Yeah, it's a little tricky. You need to combine the P=VI and V=IR formula to create the one you need. You have a power P (0.5 W), and a resistance, R (1kΩ) and you want to find a voltage, V. That means you want to...

Conservation of momentum: Initial momentum = 0 = final momentum = mgun vgun - mbullet vbullet Solve for the recoil speed of the gun: vgun = vbullet mbullet / mgun They give you the bullet's speed and the masses. Plugnchug.

You probably use either the Clausius-Clapeyron equation, or its modified form, the Antoine equation (for slightly greater accuracy). Use which ever equation for which you have data for chlorine. These equations express saturation...
