3/5, 1, 13/8, 9/5 this is the answer to your question
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:
0.43 yards is the answer
Step-by-step explanation:
Answer:
z=13
Step-by-step explanation:
Ok we are to solve for z from the given equation
2z=26
It's like making z the subject of formula
We will be able to think fast on how to make z the subject of formula from the equation
To make z the subject of formula we will have to divide both sides by 2
z=13
Therefore the value of z is 13
To solve this kind of question you must be to think on ways to eliminate the number behind the required number
Hope you understand
