Answer:
Explanation:
10.11 g sample of 
contains 22.34% 
by mass
According to the law of constant composition the if one sample of has 22.34% of by mass then any other sample of will have the same percentage of the amount of .
For a sample of 7.09 g we have
The mass of sodium in the required sample is .
