Calculate the volume of `NO_(2)` formed at S.T.P. and weight of copper oxide formed in grams when 1.88 g of copper nitrate crystals decompose as:
`2Cu(NO_(3))_(2)overset(Delta)to2CuO+4NO_(2)+O_(2)`
[Cu = 64, N = 14, O = 16]

Explanation

To solve the problem step by step, we will first calculate the molecular weights of copper nitrate and copper oxide, then determine the amount of copper oxide formed and the volume of nitrogen dioxide produced at STP.

### Step 1: Calculate the molecular weight of copper nitrate (Cu(NO₃)₂)

The molecular formula for copper nitrate is Cu(NO₃)₂. We can calculate its molecular weight as follows:

- Atomic weight of Cu = 64 g/mol
- Atomic weight of N = 14 g/mol (2 nitrogen atoms)
