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:
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
Step-by-step explanation:
Answer:
81 sodas and 50 hotdogs
Step-by-step explanation:
131 = x + x - 31
131 <em>+</em><em> </em><em>3</em><em>1</em><em> </em>= x + x - 31 <em>+</em><em> </em><em>3</em><em>1</em>
162 = x + x
x = 81
131 = 81 + (81 - 31)
131 = 81 sodas + 50 hot dogs
