Assuming that the smallest measurable wavelength in an experiment is 0.330 fm (femtometers), what is the maximum mass of an object traveling at 157 m·s^1 for which the de Broglie wavelength is observable? mass = ? kg
What volume of the solution in 5a would be necessary to react completely with 23.00mL of 0.549M NH3 according to the equation: NiSO4+6NH3 -> [Ni(NH3)6]SO4 The molarity of ta is 1.667 x 10^-4M
What is the point of inflection of the function f(x)=x^3-8x^2+5x+50? Is the local extrema at f(1/3)=50.8 max and f(5)=0 min? For the second derivative I got f(x)=6x-16 and then got x=16/6 when set to zero.

In this problem, your answers should be mathematical expressions involving a variable. Consider an ideal gas with an absolute temperature of T1 To what temperature would you need to heat the gas to double its pressure? T2=? I got T2=2P but it is wrong
It is 65.4g/mol
P=.995atm V=.205L n=? R=.0821 Lxatm/molxk) T=298K
