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

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

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
