Explanation:
The given data is as follows.
            = 10 mM =
 = 10 mM =  M
 M
            = 750 ml,
 = 750 ml,            = 5 ml
 = 5 ml
            = ?
 = ?
Therefore, calculate the molarity of given NaCl stock as follows.
                   
                   
                     = 1.5 M
 = 1.5 M
Thus, we can conclude that molarity of given NaCl stock is 1.5 M.        
 
        
             
        
        
        
Answer:
Nearly all of the water astronauts drink and shower with comes from their urine and sweat. Storage is hard to come by aboard the International Space Station. Even if a rocket had room to ferry thousands of pounds of water and oxygen to supply a six-month mission, you'd struggle to find anywhere to stash it.
