Answer is: hydrogen (H).

Main sequence stars fuse hydrogen atoms to form helium atoms in their cores.

About 90 percent of the stars in the universe are main sequence stars.

Nuclear reaction is in the inner core of the Sun and hydrogen is conveted into helium.

The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.

Mashutka [201]

Answer:

The density of the metal is 0.561 g/mL

Explanation:

The computation of the density of the metal is shown below;

As we know that

The Density of the metal is

= \frac{mass}{volume}

where,

Mass = 4.9g

Change in volume = 6.9 mL

Now place these values to the above formula

So, the density of the metal is

= \frac{4.9g}{6.9mL}

= 0.561 g/mL

Hence, the density of the metal is 0.561 g/mL

We simply applied the above formula so that the correct density could arrive
