Answer:
r=-7
Step-by-step explanation:
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>
It takes 8 minutes
The robot can complete 7.5 tasks in an hour
"Quantitative" information is information that consists of numbers
and tells you the measure (quantity) of something.
The cost, mileage, and weight of the car are all quantitative items.
The model of the car may have numbers in it, but it doesn't tell
the measure of anything. It isn't quantitative data.
