Answer:
The claim is untrue.
Explanation:
Given the information from the question. We need to evaluate the claim.
According to the phase rule we have F= C-P+2
In this particular situation, the forms are completely allotropic .In order words, they are conjured through the same chemical composition. Thus constituents C= 1, P=4 for four phases and the number variables is 2. As a result, F= C-P+2 =1-4+2= -1. Therefore, the claim is untrue.
The average atomic mass of sodium is 22.99. The average atomic mass of chlorine is 35.451. NaCl has one of each, which adds up to atomic mass of 58.441 atomic mass units. To find out how much of that is sodium, do 22.99÷58.441. you get 0.3933. So you know in any amount of NaCl, sodium makes up 39.33%. 39.33% of 50 is 19.665 g, so the answer is 19.665 g.
