Naphthalene sublimation rate=3*10^-5/min. Volume of room=60m^3. How would I calculate the naphthalene concentration in the air of the room? Ayuda me sale error al intentar subir una foto a mi pregunta :((? Let X1 & X2 have joint pmf p(x1, x2)=(x1x2)/36. 0 otherwise Find joint pmf of Y1=X1X2 and Y2=X2? A 25.0mL solution containing .60M HCl was titrated with 0.50M NaOH. Calculate the pH before the titration and at equivalence point? Differentiate(t) = (cos^3 t+ 3cost +7)^9?
