Given the density of ethanol = 0.79
Volume of ethanol = 75.0 mL
Calculating the mass if ethanol from density and volume:

Molar mass of ethanol = (2*atomic weight of C)+(6*atomic weight of H)+(1*atomic weight of O)
=(2*12g.mol) + (6*1g/mol) + (1*16g/mol)
=46g/mol
Moles of ethanol = 
Volume of the solution = 250.0 mL
Converting the volume from mL ot L:

Molarity of ethanol in the solution = 
Answer:
climbing up into the canopy
Explanation:
Answer:Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as "mudstones." ... "Fissile" means that the rock readily splits into thin pieces along the laminations.
