The answer to your question is: 58.4 g of NaCl

Explanation:

Data

Volume = 200 ml = 0.2 l

Concentration = 5M

MW = 58.4 g

mass NaCl = ?

Formula

             Molarity = (# of moles ) / volume

             # of moles = Molarity x volume

             # of moles = 5 x 0.2

             # of moles = 1

              58.4 g 1 mol

              x            1 mol

              x = (1 x 58.4) / 1

             x = 58.4 g of NaCl

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
