### 8. Savol:
**0,2 litr eritmada 94,5 g $$ \mathrm{HNO}_{3} $$** bor. Shu eritmaning normal konsentratsiyasini toping.

**H₁:**
- **Molring kislota massasi (HNO₃):**
  $$
  \text{H} = 1 \, \text{g/mol}, \, \text{N} = 14 \, \text{g/mol}, \, \text{O} = 16 \times 3 = 48 \, \text{g/mol}
  $$
  $$
  \text{M(HNO}_3\text{)} = 1 + 14 + 48 = 63 \, \text{g/mol}
  $$

- **Mol sonini hisoblash:**
  $$
  \text{Mol} = \frac{94,5 \, \text{g}}{63 \, \text{g/mol}} = 1,5 \, \text{mol}
  $$

- **Normalitati:**
  $$
  \text{Normality (N)} = \frac{\text{Ekvivalentlar}}{\text{Hajm (L)}} = \frac{1,5 \, \text{eq}}{0,2 \, \text{L}} = 7,5 \, \text{N}
  $$

**Javob: D) 7,5**

### 9. Savol:
**0,8 litr eritmada 100,8 g $$ \mathrm{HNO}_{3} $$** bor. Shu eritmaning normal konsentratsiyasini toping.

**H₁:**
- **Mol sonini hisoblash:**
  $$
  \text{Mol} = \frac{100,8 \, \text{g}}{63 \, \text{g/mol}} = 1,6 \, \text{mol}
  $$

- **Normalitati:**
  $$
  \text{Normality (N)} = \frac{1,6 \, \text{eq}}{0,8 \, \text{L}} = 2 \, \text{N}
  $$

**Javob: C) 2**

### 10. Savol:
**0,35 litr eritmada 88,2 g $$ \mathrm{HNO}_{3} $$** bor. Shu eritmaning normal konsentratsiyasini toping.

**H₁:**
- **Mol sonini hisoblash:**
  $$
  \text{Mol} = \frac{88,2 \, \text{g}}{63 \, \text{g/mol}} = 1,4 \, \text{mol}
  $$

- **Normalitati:**
  $$
  \text{Normality (N)} = \frac{1,4 \, \text{eq}}{0,35 \, \text{L}} = 4 \, \text{N}
  $$

**Javob: B) 4**
### 8. Savol: 0,2 litr eritmada 94,5 g $$ \mathrm{HNO}_{3} $$ bor. Shu eritmaning normal konsentratsiyasini toping. **Javob: D) 7,5** --- ### 9. Savol: 0,8 litr eritmada 100,8 g $$ \mathrm{HNO}_{3} $$ bor. Shu eritmaning normal konsentratsiyasini toping. **Javob: C) 2** --- ### 10. Savol: 0,35 litr eritmada 88,2 g $$ \mathrm{HNO}_{3} $$ bor. Shu eritmaning normal konsentratsiyasini toping. **Javob: B) 4**
