Answer:
90.10 g
Explanation:
Step 1: Given data
Number of molecules of water: 3.011 × 10²⁴ molecules
Step 2: Calculate the moles corresponding to 3.011 × 10²⁴ molecules of water
We will use Avogadro's number: there are 6.022 × 10²³ molecules of water in 1 mole of molecules of water.
3.011 × 10²⁴ molecules × (1 mol/6.022 × 10²³ molecules) = 5.000 mol
Step 3: Calculate the mass corresponding to 5.000 moles of water
The molar mass of water is 18.02 g/mol.
5.000 mol × 18.02 g/mol = 90.10 g

Explanation:
The synthesis of aspirin an esterification reaction. This is a substitution reaction in which an alcohol (the –OH group in salicylic acid) reacts with acetic anhydride to form an ester, aspirin.
The equation provided above is balanced by making sure all the atoms of the reactants are equal to those of the products. 1mole each of reactants was required and one mole each of the products was formed.
In the equation above:
REACTANT: C = 11, H = 12, O = 6
PRODUCT: C = 11, H = 12, O = 6
Showing they are balanced.
