A compound which contains one atom of X and two atoms of Y for each three atoms of Z is made by mixing 5.00 g of X, 1.15 xx 10^(23) atoms of Y and 0.03 mole of Z atoms. Given that only 4.40 g of the compound is formed. Calculate the atomic weight of Y if the atomic weights of X and Z are 60 and 80 amu respectively.

Find the foot and hence the length of the perpendicular from P(5,7,3) to the line (x-15)/3=(y-29)/8=(z-5)/-5 .Find also the equation of the plane in which the perpendicular and the given straight line lie.
