1.	A crystalline solid has a cubic structure in which tungsten (W) atoms are located at the cube corners of the unit cell,oxygen atoms atthe cube edgesand sodium atom at the cubecentre. The molecular formula of the compund is
Answer» `Na_(2)WO_(3)` `NaWO_(4)` `NaWO_(3)` `Na_(2)WO_(4)` Solution :No. of W ATOMS=`8times1/8=1` No. of O atoms=`12times1/4=3` No. of NA atoms=`1times1=1` ltbnrgt FORMULA of COMPOUND: `NaWO_(3)`.
