Answer: 0.65
Step-by-step explanation:
15
Step-by-step explanation:
A negative number being subtracted makes it positive
5 - -10
5+10 =15
To solve this problem, all we need is the conversion
factor.
We know that there are:
1 liter = 202.884 teaspoons
Therefore the mass of Phenobarbital is:
mass = (2 grams / 1 Liter) * (1 teaspoon) * (1 Liter /
202.884 teaspoons)
<span>mass = 0.00986 g = 9.86 x 10^-3 g = 9.86 mg</span>
If u man just simplifying it
B^8+c^10 (just add exponents)
