A chalice contains a 2.01M solution of ammonium chlorite in 2.36 liters of solvent - calculate the number of moles.

4.74 mol

Explanation:

Molarity =

2.01 M =

(2.01 M)(2.36 L) = 4.74 mol

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.

the dissolution of polymer can be thermodynamically described in 2 steps.
