The patient recieves 2.4 g Tigan in 2 days
Further explanation
In finding the conversion units, we can multiply and eliminate the same units so that we can get the desired quantity or unit.
In this case, it is expected that the number of Tigan is known in 2 days, so we just need to multiply the numbers that are known
[tex]\tt =300\dfrac{mg}{capsules}\times \dfrac{1~capsules}{dose}\times 4.0\dfrac{doses}{day}\times 2.0~days\\\\=300\times 1\times 4.0\times 2.0~mg=2400~mg=\boxed{\bold{2.4~g}}[/tex]
