(5) `CH_(3) - CO - CH_(2)I` (6) `CH_(3) - CO - O - CO - CH_(3)`
(7) `CH_(3) - CO - O - CH_(3)` (8) `CH_(3) - CO - Cl`
(9) `CH_(3) - CHOH - CH_(2) - CH_(3)` (10) `CH_(3) - CO - CH_(2) - CHOH - CH_(3)`

Answer

To determine how many of the given compounds would give a positive iodoform test, we need to identify which of these compounds contain a methyl ketone group (CH3C=O) or a secondary alcohol that can be oxidized to a methyl ketone. The iodoform test is positive for compounds that contain these functional groups.

### Step-by-Step Solution:

1. **Identify the Compounds**:
- (1) `s CH₃ - CO - CH₂ - CO - OCH₃`
- (2) `C₆H₅ - CO - CH₂ - CO - C₆H₅`
- (3) `CH₃ - CHCl - CH₂ - CH₃`
- (4) `CH₃ - CHNH₂ - CH₃`
- (5) `CH₃ - CO - CH₂I`
- (6) `CH₃ - CO - O - CO - CH₃`
- (7) `CH₃ - CO - O - CH₃`
- (8) `CH₃ - CO - Cl`
- (9) `CH₃ - CHOH - CH₂ - CH₃`
- (10) `CH₃ - CO - CH₂ - CHOH - CH₃`

2. **Analyze Each Compound**:
- **Compound (1)**: `s CH₃ - CO - CH₂ - CO - OCH₃` - Contains a methyl ketone (CH₃C=O). **Positive**
- **Compound (2)**: `C₆H₅ - CO - CH₂ - CO - C₆H₅` - No methyl ketone or secondary alcohol. **Negative**
- **Compound (3)**: `CH₃ - CHCl - CH₂ - CH₃` - Contains Cl instead of OH. **Negative**
- **Compound (4)**: `CH₃ - CHNH₂ - CH₃` - Contains NH₂ instead of OH. **Negative**
- **Compound (5)**: `CH₃ - CO - CH₂I` - Contains a methyl ketone (CH₃C=O). **Positive**
- **Compound (6)**: `CH₃ - CO - O - CO - CH₃` - This is an ester. **Negative**
- **Compound (7)**: `CH₃ - CO - O - CH₃` - This is also an ester. **Negative**
- **Compound (8)**: `CH₃ - CO - Cl` - Contains a methyl ketone (CH₃C=O). **Positive**
- **Compound (9)**: `CH₃ - CHOH - CH₂ - CH₃` - Contains a secondary alcohol that can be oxidized to a methyl ketone. **Positive**
- **Compound (10)**: `CH₃ - CO - CH₂ - CHOH - CH₃` - Contains a methyl ketone (CH₃C=O). **Positive**

3. **Count the Positive Results**:
- Positive for compounds: (1), (5), (8), (9), (10)
- Total positive results = 6

### Final Answer:
The total number of compounds that would give a positive iodoform test is **6**.
