An organic compound 'A' having molecular formula `C_(5)H_(10)O_(6)` on acetylation forms a compound having molecular weight 334. Number of hydroxy group (-OH) in the compound 'A' is:

Explanation

To determine the number of hydroxy groups (-OH) in the organic compound 'A' with the molecular formula \( C_5H_{10}O_6 \), we can follow these steps:

### Step 1: Calculate the Molecular Weight of Compound 'A'
The molecular weight of compound 'A' can be calculated using the molecular formula \( C_5H_{10}O_6 \).

- Carbon (C): 5 atoms × 12 g/mol = 60 g/mol
- Hydrogen (H): 10 atoms × 1 g/mol = 10 g/mol
- Oxygen (O): 6 atoms × 16 g/mol = 96 g/mol
