Answer 1

To calculate the required volume, we can use the formula:
Volume (mL) = (Required dose (mg) / Stock dose (mg/mL))

Given that the required dose is 80mg and the stock dose is 40mg/10mL, we can substitute these values into the formula:

Volume (mL) = (80mg / 40mg/10mL)

First, we simplify the fraction in the denominator:
Volume (mL) = (80mg / 4mg/mL)

Next, we divide the required dose by the stock dose:
Volume (mL) = 20 mL

Therefore, the volume required is 20 mL.
