Question

17 formula 1 punto convert 223 gallons to liters. use 1 gal = 3.7 l. express your answer with 1 decimal place. respuesta 18 elección múltiple 1 punto what is the definition of pressure? force applied per unit area. the relative size of particles. the average kinetic energy of particles. the amount of space a substance occupies. 19 formula 1 punto what is the mass of an unknown object whose volume is 22.6 ml and density is 9.2 g/ml? express your answer with 1 decimal place. respuesta 20 formula 1 punto what is 160 g to mg? respuesta

Explanation:

17.

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

$223\times3.7 = 825.1$

Pressure is defined as the force applied per unit area. This is a fundamental concept in physics.

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume. We can re - arrange it to solve for mass: $m =
ho\times V$.

Step2: Substitute values

Given $
ho = 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:

$825.1$
