How many grams of sodium chloride are required to make a 1.0 l solution with a concentration of 3.5 m? a. 205 grams b. 0.205 grams c. 3.5 grams d. 59 grams

Hey there!

Molar mass NaCl = 58.44 g/mol

Number of moles of solution:

n = M * V

n = 3.5 * 1.0

n = 3.5 moles of NaCl

Therefore:

1 mole NaCl 58.44 g

3.5 moles mass ( NaCl ) ??

Mass ( NaCl ) = 3.5 * 58.44 / 1

Mass ( NaCl ) ≈ 205 grams

Answer A

Hope that helps!

thats not the answer u need to drop the right one bruh
