1. 90.0 mL of distilled water is added to a 10.0mL sample of 0.150mol/L sodium
chloride. The resulting solution can be described as more
a. dilute
b. concentrated
c. Acidic
d. basic

dilute

Explanation:

A concentrated solution which is used to prepare solutions of lower concentrations by diluting it with addition of water.

A dilute solution is one which contains lower concentration.

Using Molarity equation:

=concentration of stock solution = 0.150 mol/L

= volume of stock solution = 10.0 ml

= concentration of dilute solution = ?

= volume of dilute solution = (10.0+90.0) ml = 100.0 ml

As the concentration is less than the original concentration, the solution is termed as dilute.

i think it is true since you can test the answer and can use observations to complete it.

the answer is 1 i believe
