Help me answer these please!? How many moles of NAOH are present in 11.5ml of 0.220 M NAOH? If 5.93g of CUNO3 is dissolved in water to make a 0.110M solution, what is the volume of the solution? If f(y1, y2) = 1/k exp(-1/2 [(y1)^2 +(y2)^2 +2y1y2 - 22y1 - 14y2 +65] represents a bivariate normal density function. Find k? Suppose 1.25mol of a gas has a pressure of 0.98atm & a temp. of 295K. Given that R is 0.082L atm mol-1 K-1, what volume will this gas occupy?
