30.0 grams of NaNO3 is dissolved in water to make a 5.00 L solution. What is the molarity of the solution?

Molarity= 0.071M

Explanation:

Molar mass of NaNO3= 23+14+(16*3)=85

n= m/M = 30/85= 0.353mol

V= 5L

Applying

n= CV

0.353= C×5

Simplify

C= 0.071M

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
