Answer:
The graph goes with the third chart
Step-by-step explanation:
Y starts at 3 and then goes up to 4,5, and then 6 while x starts at 0 and goes up to 1,2, and 3
Answer:
1. 35 2. 565.5 3. 12.28
Step-by-step explanation:
1. Triangle 1 & 2: 7x3=21
You do not have to divide by 2 is since there are two triangles.
Semi-circle: 14.13
2. Trinagle: 29x19/2 = 275.5
Rectangle: 29x10 = 290
3. Triangle: 3x4/2 = 6
Semi-circle: 3.14x4/2 = 6.28

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
