the answer is: Its total mass is 46 u: How does this help us measure out 6.022 x 1023 molecules of ethanol? As we said before, 1 g = 6.022 x 1023 u. Therefore we only need to measure 46 g of ethanol to get 6.022 x 1023 molecules or 1 mol of ethanol.

A The molecular formula of ethanol may be written in three different ways: CH3CH2OH (which illustrates the presence of an ethyl group, CH3CH2−, and an −OH group), C2H5OH, and C2H6O; all show that ethanol has two carbon atoms, six hydrogen atoms, and one oxygen atom.

A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).
