Question

question 4 (1 point)
what is the molar mass of acetic anhydride? use the periodic table above. your answer will be in g/mol with two decimal places but do not include the units in your response.

Explanation:

Step1: Determine the chemical formula of acetic anhydride

The chemical formula of acetic anhydride is \(C_4H_6O_3\).

Step2: Find the atomic masses of each element

From the periodic table:

• The atomic mass of \(C\) (carbon) is \(12.01\space g/mol\)
• The atomic mass of \(H\) (hydrogen) is \(1.008\space g/mol\)
• The atomic mass of \(O\) (oxygen) is \(16.00\space g/mol\)

Step3: Calculate the molar mass

For \(C_4H_6O_3\):

• Mass from \(C\): \(4\times12.01 = 48.04\)
• Mass from \(H\): \(6\times1.008=6.048\)
• Mass from \(O\): \(3\times16.00 = 48.00\)
• Molar mass \(M=48.04 + 6.048+48.00\)

$$M=102.09$$

Answer:

102.09
