Answer:
hmmmmm i need more details <3
43% of 166 is 71.38 so it would be 71 to the nearest whole number!
-3+7=4
-10-2=-12
4 > -12
-3+7 > -10-2
Answer:
1,3,7,13,21,31,43,57
Step-by-step explanation:
It s increasing by two each time.
1+2=3
3+4=7
7+6=13
etc.
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
