The molecular weight of NaCl is 58.44 grams/mole. If you had a 1.0 molar solution (1.0 M), you would have to put 58.44 g of salt in 1.0 liter of solution. How many moles of NaCl would you have in 100 mL of this solution

Sienna Roman · Answer 1

0.1 moles of NaCl are contained in 100 mL of solution

Explanation:

To determine the answer for this question we can make an easy rule of three:

The solution is compounded by:

1 mol of NaCl in 1L of solution

M = 1M → Moles of solute which are contained in 1L of solution

M, means molarity. This is a sort of concentration for solutions

Therefore, in 1000 mL we have 1 mol of NaCl

So, in 100 mL we must have (100. 1) / 1000 = 0.1 moles of NaCl
