## A pharmacist dilutes 100ml of Clorox with 1 quart of water Express the concentration of Sodium Hypochlorite in the final dilution as a W/V ratio.

Commercial Clorox containsi5.25% W/V Sodium Hypochlorate:

**a-**1/9**b-**1/10**c-**1/100**d-**1/180**e-**1/200***

### The concentration of Sodium Hypochlorite in the final dilution is 1/200.

#### Calculation:

- Volume of Clorox: 100 ml
- Volume of water: 1 quart = 946 ml
- Concentration of Sodium Hypochlorite in Clorox: 5.25% W/V

#### Total volume of the solution:

- Total volume = Volume of Clorox + Volume of water = 100 ml + 946 ml = 1046 ml
- Concentration of Sodium Hypochlorite in the final solution:
- Concentration = (Concentration of Sodium Hypochlorite in Clorox) * (Volume of Clorox) / Total volume
- Concentration = (5.25% W/V) * (100 ml) / (1046 ml) = 0.5019120458891013% W/V

#### W/V ratio:

- W/V ratio = Mass of Sodium Hypochlorite / Volume of solution
- W/V ratio = (0.5019120458891013% W/V) * 1046 ml = 0.5272374833948006 grams
- W/V ratio = 0.5272374833948006 grams / 1046 ml = **1/200

Therefore, the concentration of Sodium Hypochlorite in the final dilution is 1/200*.
