When we look at the periodic table, it tells us the Sodium is labeled as 'Na'.
Answer:
Yes chemistry. Try to add then multiply the top. Get the moles and you will find it.
Explanation:
Try to add then multiply the moles in the equation
I believe it’s B. At least thats what makes sense for me.
<h2>Answer:</h2>
The volume of water measured using the graduated cylinder is <em>not exactly identical </em> identical to the volume calculated.
<h3>Explanation:</h3>
Calculated volume is theoretical value calculated from the density and mass of water.
But volume measured in cylinder can contain the personal error of individual.
Because in graduated cylinder volume is measured in a specific way that is:
- Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid.
- The liquid will tend to curve downward.
- This curve is called the meniscus.
- Always read the measurement at the bottom of the meniscus.
Hey there!
To find the density of an object, you must use this formula:
Density=Mass/Volume
Knowing that your mass is 128.3741, the only information you need left would be to find the volume of the cube.
Because the side length of the cube is given, you can multiply the length three times in order to find its volume:
1.25*1.25*1.25
=1.953125
Now that you have your volume and mass, divide the mass by the volume to find the density:
128.3741/1.953125
=65.7275392
Therefore, your density would be 65.7275392 grams per inches cubed.
