75g of active agreement powder is mixed with 300 ml normal saline. What is the final percent strength(w/V)? ____________

75 x (100/300) = 25%?

75/300 x 100 = % strength

0.25 x 100= 25 % is the percent strength

To determine the final percent strength (w/V), we need to calculate the weight of the agreement powder in the solution and divide it by the volume of the solution.

1. Convert 300 ml to liters: 300 ml = 300/1000 = 0.3 L

2. Calculate the weight of the agreement powder in the solution:
- 75g agreement powder

3. Determine the final percent strength (w/V):
- (Weight of agreement powder / Volume of solution) × 100
- (75g / 0.3 L) × 100 = 250 g/L (expressed as g/L)

Therefore, the final percent strength (w/V) is 250 g/L.

To calculate the final percent strength (w/v), we need to find the ratio of the weight of the active ingredient to the volume of the solution. Here's how we can find the answer step-by-step:

Step 1: Convert the volume of normal saline from milliliters (ml) to liters (L).
300 ml = 300/1000 = 0.3 L

Step 2: Calculate the weight/volume ratio in grams per liter (g/L).
Weight of active ingredient (g) = 75g
Volume of solution (L) = 0.3 L
Weight/volume ratio (w/v) = (Weight of active ingredient / Volume of solution) × 100
w/v = (75g / 0.3 L) × 100 = (250 g/L) × 100

Step 3: Convert grams per liter (g/L) to percent strength (w/v).
Percent strength (w/v) = (Weight/volume ratio / 10) = 250/10 = 25%

Therefore, the final percent strength (w/v) of the solution is 25%.
