. Let's say you are making 500.0 mL of a 2.0 M solution of NaCl. You have measured out the appropriate grams of NaCl, added it to the volumetric flask and added water up to the 500.0 mL mark. Which of the following errors would cause your molarity to be LESS than the 2.0 M of NaCl that you planned for?

Molar concentration can be used to convert between the mass or moles of solute and the volume of the solution. Introduction: Mixtures and solutions. In real life, we .

Explanation:

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.

a polar bond is formed when electrons are shared unevenly between atoms
