80% carbon and 20.% is hydrogen
Answer:
<h2>406 K</h2>
Explanation:
To convert a temperature from degree Celsius to Kelvin add 273 to the value in degree Celsius
That's
K = 273 + °C
where
K is the temperature in Kelvin
°C is the temperature in degree Celsius
From the question we have
K = 273 + 133
We have the final answer as
<h3>406 K</h3>

Answer:-
Solution:- It is a unit conversion where it asks to convert kg of He to atoms. We need to convert kg to grams, grams to moles and finally moles to atoms.
We know that, 1 kg = 1000 g
Molar mass of He is 4.0 grams per mole and 1 mole of an atom equals to Avogadro number of atoms.
The set up would be as given below:

= 
So, there are
of He in it's 536 kg.
All atoms of the same element have the same
number of protons. Every atom also has a nucleus.
