Answer:
O volume of the solution
Explanation:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / volume of solution in L
For example:
if we dissolve the 1 mole of NaCl to make the solution of volume 2 L. The molarity of solution is,
M = 1 mol / 2 L
M = 0.5 M
Answer:
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
Explanation:
Number of slices of ham = 231
Given that each sandwich has 1 slice of ham.
Then 231 slices of ham will be in :
![1\times 231 =231 sandwiches](https://tex.z-dn.net/?f=1%5Ctimes%20231%20%3D231%20sandwiches)
A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :
![231\times 2=462](https://tex.z-dn.net/?f=231%5Ctimes%202%3D462)
Each bread slice is applied with 0.0500 ounce of mayonnaise.
Then 462 bread slices will have :
![462\times 0.0500 ounces=18.48 Oz](https://tex.z-dn.net/?f=462%5Ctimes%200.0500%20ounces%3D18.48%20Oz)
1 bread loaf = 13 bread slices
Then breads loves in 462 bread slices :
![\frac{462}{13}=35.54\approx 36](https://tex.z-dn.net/?f=%5Cfrac%7B462%7D%7B13%7D%3D35.54%5Capprox%2036)
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
0.086mole
Explanation:
The problem is very simple. It involves conversion from mass to number of moles of NaCl
What is mole?
A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.
How is it related and can be converted from mass;
Number of moles of a substance = ![\frac{mass}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D)
Since we know the mass, we can find the molar mass and put into this equation;
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
Number of moles of NaCl =
0.086mole
