State how you would prepare each solution: 1) 455g of a solution of C3H5(OH)3 in water in which the mole fraction of glycine is .250 2) 755g of 1.4 molality solution of napathalene C10H8 in benzene C6H6. My instructor told us to find the amount of grams i...

An ion beam has a cross-sectional of 2.5 mm^2 and the charge delivered by it to a target can be expressed as q(t)=(.12 C/s^3)t^3 + (.24 C/s^2)t^2 - .45 C. Calculate the current density in the beam at t = 3.0 seconds. I used an integral from 0 to 3s. and g...

The terminal voltage of a battery is 5.0V when 0.55A current is drawn from it, whereas the terminal voltage is 5.7V when a current of 0.180A is drawn. The emf of the battery is? The formula I used was V_(ab) = Emf - I*r First finding the r by taking the d...

Ah I see, thank you so much.
