Answer:
we have 1 cal in 0.2grams (16/80)
so in 100 cal, it is 0.2x100 = 20 grams
Both the numerator and denominator have a 9 and a "b" in common, so we can reduce the fraction to:
3c/4d
Answer is B. second one
A = 1/8, B = 5/16, C = 7/12, D = 5/6
--------------
X = total amount of people
80% of x = 540
.8x = 540
x = 675
There were 675 people
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>
