If you had 0.867 miles of salt, NaCI , in a 0.69 L solution, what would be the molarity

Approximately . (Assuming that the question says moles of salt in this solution.)

Explanation:

The molarity of a solution gives the quantity of the solute in every unit volume of the solution. In this question:

Note that in this question, liter is the unit for the volume of the solution. The molarity of the solution should thus give the amount of solute in every liter of the solution:

.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
