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
Answer:
The directions for a homemade glass cleaner call for 1 part vinegar to 4 parts water. Mr. Gilbert mixed 2 cups of vinegar with 5 cups of water. Did he use a correct ratio of vinegar to water? Explain.
So pretty much for the first question it is line A since the steeper the line the faster something goes as in this case A is covering the most questions at the fastest rate.
For the second one it’s none of the above because 3680/4=920.
Hopefully I don’t get this wrong :/
