Answer:
0.670. M
Step-by-step explanation:
Molarity can be expressed like this:
molarity
= number of moles
/volume (L)
We know the volume, which is 2.37 L
, but we need to find the number of moles. We can do this by dividing 67.3 g by the molar mass of L
i
C
l
:
number of moles =
mass of sample
/molar mass
number of moles = 67.3 g
/(6.94 + 35.45) g/mol =
67.3 g
/42.39 g/mol
number of moles = 1.59 mol
molarity
=
1.59 mol
/2.37 L
= 0.670. M
I think the answer might be B. $4,754.60 but I'm not sure. Sorry
Answer:
I think the number on top will be 3
I think y = (-23.8)
y=2+4.3x and let x=(-6) so y=2+(4.3 * -6) so y=2+ (-25.8) so y=2-25.8 so y= (-23.8)
