Final answer:
To calculate the volume of stock solution needed, we can use the formula: (stock concentration) x (stock volume) = (desired concentration) x (desired volume). In this case, the stock concentration is 2g per 10 ml, and the desired dose is 5000mg. Solving for stock volume, we find that the stock volume needed is 250 ml.
Step-by-step explanation:
To calculate the volume of stock solution needed, we can use the formula: (stock concentration) x (stock volume) = (desired concentration) x (desired volume). In this case, the stock concentration is 2g per 10 ml, and the desired dose is 5000mg. We can set up the equation as: (2g/10 ml) x (stock volume) = 5000mg. Solving for stock volume, we find:
(2g/10 ml) x (stock volume) = 5000mg
Dividing both sides by 2 and then multiplying by 10, we get:
stock volume = (5000mg x 10 ml) / 2g
Simplifying further, we find that the stock volume needed is 250 ml.
