250mL/100mL=1.5 36g * 2.5=90g 90 grams KCl (potassium chloride) will be needed to make a saturated solution in 250 mL of water at 40 degrees C.

Sorry, another question. A camper van with a mass of 2500kg has a maximum driving force of 2650N. The camper van drives along a straight, level road at a constant speed of 90 kilometres per hour. At this speed, air resistance is 2000N and the frction between the tyres and road...

Ahh ok, thank you very much!

Physics
A spacecraft launches a probe at a constant speed. A day later, the probe returns at the same speed. Did the probe have to burn any fuel?

Ok, thank you. I was wondering if the several masses had something to do with the surface being ice?

physics
A space probe lands on the icy surface of Europa, a moon of Jupiter. It weighs a set of known masses. The results are shown below. Mass (kg) 0.1 0.2 0.3 0.4 0.5 Weight (N) 0.15 0.30 0.36 0.55 0.68 a) i) Plot a graph of this data on the axes given (done) ii) Use your graph to e...
