If you have 0.2 moles of NaCl in 0.5 L of solution, what is the molarity? (Round answers to the nearest hundredth)

Molarity = 0.4 moles per Liter

Step-by-step explanation:

If you have 0.2 moles of NaCl in 0.5 L of solution, what is the molarity? (Round answers to the nearest hundredth)

The formula formula Molarity

= n/v

Where n = number of moles

v = volume in liters

Hence

Molarity = 0.2 moles/0.5L

= 0.4 moles per Liter

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
