The equation for density is:

where the mass is in grams and the volume is in
.
We are given 4,000 kilograms, and we know that there are 1,000 grams in 1 kilogram, so we need to multiply to convert to grams:

We are also given 0.5
, and we need to convert to
. We know that there are 100 cm in 1 m, and since we are talking about cubic volume, we must also raise 100 to the 3rd power:
. So now we know that there are 1,000,000
in 1
. We need to then multiply 1,000,000 cm by 0.5 in order to find the volume that was given in the question:

So now that we have the correct units, let's plug them into the equation:


So now we know that the density is 8g/cubic centimeter.
A frog heart has 3 chambers, 1 ventricle and 2 atria. One atrium (the right) receives deoxygenated blood from the frog's body (in the systemic circulation) and then pumped to the single ventricle wherein it will go to the lungs to be oxygenated. Another atrium (the left) received oxygenated blood from the lungs then pumped to the single ventricle wherein it will go to the systemic circulation. In the single ventricle, some form of mixing of the oxygenated and deoxygenated blood happens but since the frog is a cold blooded animal, the decrease in the concentration of oxygen is deemed superficial.
This advancement allows the frog to live on land using the lungs as the primary organ for oxygenation of the blood.
Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.
<h3>How is the Lewis structure?</h3>
The Lewis structure shows the formation of bonds in a molecule, as well as the atoms involved and the valence electrons of each of them. Atoms form chemical bonds with each other in order to achieve electronic stability.
With this information, we can conclude that Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.

Hey there!
First when adding fractions, you have to have the same denominator
So, the least common multiple or LCM is 12 because
6, 12
And
4, 8, 12
They both match at 12 so that is the LCM or denominator.
Now since you multiplied 6 * 2 = 12 and 3 * 4 = 12
Multiply the numerator by the same number.
So 1/6 * 2 = 2/12
And
3/4 * 3 = 9/12
<u>Your answer is 11/12</u>
Hope this helps
