The sandstone is older.in order for the granite to have been formed with sandstone in its precnese then it had to have already exsisted in that area..making it older.
Skin cell serves a completely different purpose. Muscle cells have large amount of mitochondria in them and are energy rich to perform functions that require movement. They are more durable than epithelial cells. Epithelial cells (skin cells) are quickly shed, quickly replaced, lack mitochondria and are mass produced by the body.
I believe it has something to do with the H2O molecules, because a chemical compound is not a mixture.
Cl is stable as a diatomic molecule where the 2 Cl atoms are held together by a covalent bond
molar mass of the diatomic molecule is 70.9 g/mol
therefore 70.9 g of Cl₂ is - 1 mol
then 140 g of Cl₂ is - 1/70.9 x 140 = 1.97 mol
there are 1.97 mol of Cl₂ present
Answer:
9256.5 g/ml
Explanation:
Use the formula,
Density = mass/volume
;Where you need to calculate the volume change firstly,
Volume = 238.0 - 207.4
;Volume = 30.6 ml
; Hence for calculating density,
; Density = 302.5 × 30.6
; Density = 9256.5 g/ml
