NEET Chemistry The Solid State Questions Solved


A solid has a structure in which W atoms are located at the carners of a cubic lattice. Oxygen atom at the centre of the edges and Na atom at centre of the cube. The formula of the compound is 

1. NaWO2

2. NaWO3

3. Na2WO3

4. NaWO4

(2) Number of 'W' atoms = 8*1/8=1(Since there are at the corners)

Number of 'O' atoms = 12*1/4 = 3(become 'O' atoms are at the centre of face edges)

Number of 'Na' atoms = 1x1=1(The Na atom is at the centre of cube)

then the formula will be NaWO3
