Answer
17.
Explanation:
Step1: Set up conversion
We know 1 gal = 3.7 L, so for 223 gal, we multiply by the conversion - factor. $223\times3.7$
Step2: Calculate result
$223\times3.7 = 825.1$
Answer:
$825.1$

Brief Explanations:
Pressure is defined as the force applied per unit area. This is a fundamental concept in physics.
Answer:
Force applied per unit area.
19.
Explanation:
Step1: Recall density formula
The density formula is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass, and $V$ is volume. We can re - arrange it to solve for mass: $m = \rho\times V$.
Step2: Substitute values
Given $\rho = 9.2$ g/mL and $V=22.6$ mL, then $m=9.2\times22.6$.
Step3: Calculate result
$9.2\times22.6 = 207.92\approx207.9$
Answer:
$207.9$
20.
Explanation:
Step1: Know conversion factor
We know that 1 g = 1000 mg.
Step2: Convert grams to milligrams
To convert 160 g to mg, we multiply by 1000: $160\times1000$.
Step3: Calculate result
$160\times1000 = 160000$
Answer:
$160000$
