Answer:
D
Explanation:
Ocean breezes keep coastal galveston cooler than Del Rio, which is inland exposed to southerly winds.
Molar concentration = (numbet of mol Solute)/ ( volume Solution)
1) Finding
the number of the mol solute


Molar mass ethanol:
C2H5OH = 12 x 2+ 1 x 5 + 16 + 1 = 46.0 g/mol
volume = 545 mL in liters: 545 / 1000 => 0.545 L
number of moles:
29.0 / 46.0 => 0.6304 moles
M = n / V
M = 0.6304 / 0.545
M = 1.156 mol/L
hope this helps!
