Potassium feldspars are common members of the alkali feldspar group and form a complete solid solution series from KAaSi3O8 through (K, Na)AlSi3O8 to NaAlSi3O8. You really need more information for a precise chemical composition as K-Feldspars can have a wide range of chemical compositions.

Do Granite and Gabbro have the same chemical composition?

No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.

What type of cleavage does feldspar have?

Plagioclase feldspar is a non-metallic mineral. It has 2 cleavages at nearly right angles. It is also differentiated from potassium feldspar because it contains striations. Potassium feldspar has 2 cleavages at nearly right angles.
