How many grams of NaCl (MW =58 g) are present in 100 ml of a 10 M solution?

Question

How many grams of NaCl (MW =58 g) are present in 100 ml of a 10 M solution?

 a, 580 g

 

 b, 116 g

 

c,  5800 g

 

 d, 58 g

 

Answer 1

The notation 10 M solution tells us that there are 10 moles per Liter of NaCl.

Since we have 100mL = 0.1 L of solution, we will have

(10 M)(0.1L) = 1 mole NaCl

From here, you can use the molar weight of NaCl to get to the correct answer.

Good luck,
