Notice its copper (I) NOT copper (II)
Write the equation of: metal oxide + oxygen --> metal oxide
} + O_{2 (g)} \rightarrow 2Cu_2O_{(s)})
You are provided with the mass of copper (I), the rest is very easy, if not look below (in white):
Step 1: Find the moles of copper (I)
Step 2: Identify the molar ratio of copper solid and copper oxide
Step 3: Convert moles
Step 4: Find mass of copper oxide
Note: U must recall a formula that relates MOLES, MASS and MOLECULAR MASS
(dont worry about limiting reagants and excess)

this is the formula man,Notice its copper (I) NOT copper (II)
