Answer:
<h2>3.31 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 23.2 g
volume = final volume of water - initial volume of water
volume = 62 - 55 = 7 mL
We have
We have the final answer as
<h3>3.31 g/mL</h3>
Hope this helps you
Answer:
Concentration of ethanol required = 48.476 M
Explanation:
Given that:
the absorption intensity = 1.00
Molarity of ethanol = 1M
NMR instrument used = 160 MHz
Temperature used = 300 K
The required concentration of ethanol can be determined as follows:
= 48.476 M
On eof the forces is inertia. This can happen when you move your furniture to clean under them. When you move an object in a straight line without chanign its composition (e.g moving a chair or a table from one side to the other) you are working with inertia. The secon force is friction. It s present when you clean a surface by rubbing it with a tool like a damp cloth or a mop.
Answer:
19 atoms
Explanation:
6 carbon, 12 hydrogen, one Nitrogen
Answer: The pressure that is needed is around 405kPa-755kPa
To summarize into 405PPM-755PPM
Explanation: In which 405 PPM-755 PPM which is about the same amount of pressure that water pressurises a car in water or a better example is that it's the same amount of pressure as if a penny was dropped from the sky towards a person holding a square piece of cardboard in which then the penny would directly go straight through the piece of cardboard.
