Answer:

3.02e23

Explanation:

carbon molecular weight = 12 g /mol

1 mol = 6.02e23 atoms

your sample, 6 g / 12 g/mol = 0.5 mol

0.5 x 6.02e23 =

bagirrra123 [75]

Answer:

3. 76 g/ml^3

Explanation:

We are given the mass of the metal pellets which is 33.4 grams. To calculate the density of the metal, we need to divide the mass by the volume. The volume of the metal is not directly given so we need to find it ourselves. The water was initially 12.7 ml and then it rose to 21.6 ml after placing the metal pellets. This indicate that the volume of the metal pellets is 8.9 ml.

21.6 - 12.7 = 8.9

We can now use the density formula.

p =  \frac{m}{v}

p =  \frac{33.42}{8.9}

p = 3.76

What is the ultimate end of a high mass star that has a core about 2.8x the mass of our sun?
jolli1 [7]

Answer:

A

Explanation:

It is formed after the star has ended its star cycle into a supernova. The star collapsed into a neutron star that is smaller than the progenitor star but has inherited angular momentum. IT, therefore, spins faster emitting electromagnetic radiation that seems to pulsate.
