Your answer is incorrect.
To calculate the amount of stock solution and diluent needed to compound this order, we can use the following equation:
stock solution volume x stock solution concentration + diluent volume x 0 = final volume x final concentration
Where:
- Stock solution volume = x (what we need to find)
- Stock solution concentration = 20.5% (given)
- Diluent volume = y (what we need to find)
- Final volume = 500 ml (given)
- Final concentration = 12%
Substituting the values in the equation, we get:
x(20.5%) + y(0%) = 500 ml (12%)
0.205x = 60
x = 292.68 ml (rounded to 293 ml)
Therefore, we need 293 ml of the 20.5% stock solution and 207 ml of diluent to compound this order.
an order is written for 500ml 12%solution. i have a 205 solution in stock.
how much stock solution and how much diluent are needed to compound this order
my answer is
300ml solution of and 200 diluent
