1.	A mother cell disintegrate into sixty identical cells and each daughter cell further disintegrate into 24 smaller cells. The smallest cells are uniform cylindrical in shape with diameter of 120 Å and each cell is 6000 Å long. Determine molar mass of the mother cell if density of the smallest cell is 1.12 g//cm^(3) :
Answer» Solution :Volume of smallest cell `pir^(2)\|=pi(60xx10^(-8)cm)^(2)` `(6000xx10^(-8)cm) = 6.785xx10^(-17)cm^(3)` mass of ONE smallest cell `=7.6xx10^(17) g` implies MOLAR mass of MOTHER cell `=7.6xx10^(-17)xx24xx60xx6.023xx10^(23)=6.6xx10^(10)"amu"`
