So since I've been given mass percentages, I'm considering a 100g sample of Ti-6Al-4V. That wouldn't change the answer, though, would it?
Thank you for being patient with me - I've never taken a thing about alloys!
So I think I've figured out what I was doing wrong. This time, I supposed that the compound was in 100g of water.
So, the mass fraction of Ti was 90/100 = 0.9
Mass fraction of Al = 6/100 = 0.6
Mass fraction of V = 4/100 = 0.4
So:
Number of moles of Ti = 90/413.52 = 0.22 moles...

Ti-6Al-4V is a metal alloy used to make biomaterials. Its composition is 90% Ti; 6% Al and 4% V (mass percentages).
(a) What are the mass fractions of Ti, Al and V?
(b) What are the mole fractions of Ti, Al and V?

Ah, I see what I did wrong. I just assumed that because they had drawn the line they way they did in the figure, the angle was 45 degrees. Silly mistake, thanks for that!
Homework Statement
(1) A point charge q1 = -2.9 μC is located at the origin of a co-ordinate system. Another point charge q2 = 5 μC is located along the x-axis at a distance x2 = 8.6 cm from q1.
The answer to this was -17.64N.
(2) Charge q2 is now displaced a distance y2 = 2.4 cm in the...
