8 gm x 3= x kg

8 gm of oxygen and x gm of hydrogen posses same pressure, volume and temperature. Then x=

Solve 3x^(4) -8x^(3) -6x^(2) + 8x + 3 = 0 .

Particles of masses 1gm, 2gm, 3gm and 4 gm are placed at x = 1 cm, x = 2cm, x = 3 cm, x = 4 cm respectively. Then X_(cm)=

An element X is found to combine with oxygen to form X_(4)O_(6) . If 8.4 gm of this element combines with 6.4 gm of oxygen, then calculate the atomic weight of X.

An element X is found to combine with oxygen to form X_(4)O_(6) . If 8.4 gm of this element combines with 6.4 gm of oxygen, then calculate the atomic weight of X.

If 16 gm of oxygen and x gm of hydrogen has the same volume at the same temperature and pressure, then find the value of x.
