Question

calculate the formula mass for copper(i) sulfate. express your answer in atomic mass units to two decimal places. formula mass = amu submit request answer

Explanation:

Step1: Determine the formula of copper(I) sulfate

Copper(I) has a charge of \(+1\) (\(Cu^+\)) and sulfate is \(SO_4^{2-}\). To balance the charges, we need 2 \(Cu^+\) ions for 1 \(SO_4^{2-}\) ion. So the formula is \(Cu_2SO_4\).

Step2: Find atomic masses

• Atomic mass of \(Cu\): \(63.55\) amu (from periodic table)
• Atomic mass of \(S\): \(32.07\) amu
• Atomic mass of \(O\): \(16.00\) amu

Step3: Calculate total mass for each element

• For \(Cu\): \(2 \times 63.55 = 127.10\) amu
• For \(S\): \(1 \times 32.07 = 32.07\) amu
• For \(O\): \(4 \times 16.00 = 64.00\) amu

Step4: Sum the masses

Formula mass \(= 127.10 + 32.07 + 64.00 = 223.17\) amu

Answer:

\(223.17\)
