Answer:

The correct answer is 2, 0M

Explanation:

We calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter):

250 ml solution----- 0,5 moles of NaCl

1000 ml solution----x= (1000 ml solution x 0,5 moles of NaCl)/250 ml solution

x=  2,0 moles of NaCl --> <em>The solution is 2 M</em>

As the volume of a gas increases, what happens to the pressure of the gas?
Elena L [17]
