Sodium hydroxide, naoh, is a strong base that is used in industrial synthesis and processes such as making paper. what is the mass of 2.80 ×1022 molecules of naoh (molar mass = 40.0 g/mol)?

1.86 g

Explanation:

We must convert formula units of NaOH to moles and then to mass of NaOH.

Step 1. Convert molecules to moles

Step 2. Convert moles to grams

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

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