The two main constituents of the sun, are both lightweight elements.
<h3 /><h3>What is constituents of the sun?</h3>
Helium and hydrogen make up the majority of the sun's mass (He). The sun is made up of 92.1% hydrogen and 7.9% helium by mass. Less than 0.1 percent of the mass of the sun is made up of different metals. The surface of the sun is around 10,340 degrees Fahrenheit hot (5,726 degrees Celsius).
The majority of the sun's emissions come from particles like neutrinos that travel beyond the light the sun's surface emits and can't be seen with ordinary spectroscopic instruments. As a result, to identify these particles, specialised equipment were needed, such as the Super Kamiokande (Kamioka Observatory, Japan), which has incredibly sensitive light sensors. These particles provided evidence that nuclear fusion processes were taking place in the Sun's core, which is what caused their emission.

<u>Answer:</u> The density of unknown material is 7.2 g/mL
<u>Explanation:</u>
We are given:
Volume of water already in the container, = 22 mL
Volume of water rise in the cylinder, V = 27 mL
Volume occupied by unknown material =
To calculate density of a substance, we use the equation:
We are given:
Mass of unknown material = 36.0000 g
Volume of unknown material = 5 mL
Putting values in above equation, we get:
Hence, the density of unknown material is 7.2 g/mL
