Question

what is the molar mass of this compound? zn(c₂h₃o₂)₂ remember to round to the hundredths place from the periodic table. 154.46 g/mol 183.48 g/mol 94.43 g/mol 189.87 g/mol

Explanation:

Step1: Determine the atomic masses

From the periodic table:

• Atomic mass of \(Zn = 65.38\space g/mol\)
• Atomic mass of \(C = 12.01\space g/mol\)
• Atomic mass of \(H = 1.01\space g/mol\)
• Atomic mass of \(O = 16.00\space g/mol\)

Step2: Calculate the molar mass of \(Zn(C_{2}H_{3}O_{2})_{2}\)

• For \(Zn\): \(1\times65.38 = 65.38\space g/mol\)
• For \(C\): \(2\times2\times12.01=4\times12.01 = 48.04\space g/mol\)
• For \(H\): \(2\times3\times1.01 = 6\times1.01=6.06\space g/mol\)
• For \(O\): \(2\times2\times16.00=4\times16.00 = 64.00\space g/mol\)

Step3: Sum up the masses

$$65.38+48.04 + 6.06+64.00=183.48\space g/mol$$

Answer:

183.48 g/mol
