Answer 2

Answer:

No.of 1/2 grains tablets that can be made from 10g of phenobarbital is 300 tablets

Explanation:

Given that,

Quantity of phenobarbital is 10 grams

Now we need to find the number of half-grain tablets that can be made from this 10gm of phenobarbital.For that we need to know a relation

$1 \: gram = 15 \: grains$

Therefore,for 10gm of phenobarbital contains
