3 Let Fx y z sin2zuz cos2 zyz Assume x is a differentiable

3. Let F(x, y, z) = sin2(zuz) + cos2 (zyz). Assume x is a differentiable function of (y, z). We know that F(x, y, 2) 1 for all (x,y,z). Use these facts to find a formula for .

Solution

3) from idealgas equation

PV = nRT

n = no of mol of CO2 = PV/RT

P = 15 atm

V = 5.5 L

R = 0.0821 l.atm.k-1.mol-1

T = 23 c = 296 k

n = (15*5.5)/(0.0821*296)

    = 3.395 mol
