Answer:
chairs at each table
Step-by-step explanation:
Total number of chairs : 300
Total number of tables : t
If we divide 300 chairs equally among t tables, then each table must have 300 chairs ÷ t tables =
chairs at each table.
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
To find the length of side of square, we have to use distance formula.
Points are (-4,-6) and (5,-1)
Formula for distance between two points.

So length of side of square is 10.3 units.
Answer: 10.3 units
