What is the mass of 0.50 moles of Na? 11 grams 46 grams 3.0 × 1023 grams 6.0 × 1023 grams
2 answers:
Answer : The mass of 0.50 moles of Na is, 11 grams
Explanation : Given,
Moles of Na = 0.50 mole
Molar mass of Na = 22.99 g/mole
Formula used :
where,
n = number of moles of Na
w = mass of Na
M = molar mass of Na
Now put all the given values in this formula, we get the mass of Na.
Therefore, the mass of 0.50 moles of Na is, 11 grams

There are types of nuclear reaction: nuclear fusion and nuclear fission. The difference is that fusion is a combination of two elements while fission is the breaking up of the subatomic particles of an element creating a new element. The limiting element to this is Iron. Iron-26 is the most stable element. As a result, elements lighter than Fe-26 are generally fusible. This includes hydrogen and helium.
This reaction is common in the stars, most especially the Sun. The energy of the Sun comes from its abundant hydrogen composition which becomes fusible into Helium. This occurs at a temperature of 14 million Kelvin. The nuclear reaction is a not a one-way step process as shown in the picture.
