Brut [27]

Answer:

b) The volume of stock solution used is less than 3 liters.

Explanation:

Given:

Concentration of stock solution of NaCl, M1 = 10 M

Concentration of diluted solution of NaCl, M2 = 1 M

Volume of diluted NaCl solution, V2 = 3 L

Let the volume of stock NaCl solution = V1

Formula:

Use the dilution relation:

M1V1 = M2V2

Based on the above equation:

V1 = \frac{M2V2}{M1} = \frac{1M*3L}{10M} = 0.3 L

Therefore, the volume of stock solution required is 0.3 L which is less than 3 L

Q: What property of propane does Rodriguez change using the burner? Support your answer with evidence from the text.
UNO [17]

Answer:

The wind is starting to blow stronger, and when you’re riding in a basket under a hot air

balloon, just 400 feet above ground, that’s not necessarily a good thing. Keith Rodriguez looks

to the horizon and squints. He had planned to take off from Scioto Downs, a horse racetrack

south of Columbus, Ohio, fly a few miles north, and land his balloon in a barren cornfield next

to his pickup truck.  

Then the wind changed. Instead of a light breeze from the south, now Rodriguez’s bright red

balloon is getting hit by stronger, colder winds from the west. He has plenty of propane fuel in

his tank—he probably could ride the wind halfway to Pennsylvania. But that would be

dangerous. Rodriguez’s choice of landing sites just became very limited. As the balloon

switches direction and floats east, everything below becomes a wide carpet of suburban

sprawl—big‐box stores, major highways, strip malls. Beyond the stores lie forests.

A sample of lead has a density of 11.3 g/cm3 and a mass of 123 grams, what is the volume of the sample?
SVEN [57.7K]

Answer:

The answer is

<h2>11.18 cm³</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 123 g

density = 11.3 g/cm³

The volume is

volume =  \frac{123}{11.3}   \\  = 11.18181818...

We have the final answer as

<h3>11.18 cm³</h3>

Hope this helps you
