mass-mass conversions and mass-mole conversions: what is the difference and how do you do each?

mass is converted to mols by mols = grams/molar mass.

mass of one chemical is converted to mass of another chemical by using the coefficients in the balanced chemical equation. For example:

CH4 + 2O2 ==> CO2 + 2H2O

16 grams CH4 converts to how many grams CO2. The molar mass CH4 is 16; the molar mass CO2 is 44.

mols CH4 = 16/16 = 1 mol
Now convert mols CH4 to mols CO2.

mols CO2=mols CH4 x (1 mol CO2/1 mol CH4) [note that I used the coefficients in the balanced equation for the coefficients in the factor of 1 mol CO2/1 mol CH4].

Now convert mols CO2 to grams CO2.
grams = mols x molar mass
grams CO2 = mols CO2 x molar mass CO2.
g CO2 = 1 x 44 = 44 g CO2.

I hope this helps.

it does- thank you so much!

in a mass-mass conversion you are given a certain amount of an elemnt in grams and you are asked to fid the mass of another substance in the balance equatin that you are given.

For example:
they want you to find the mass of water in the chemical equation in which glucose is changed to water and carbon dioxide.
C6H12O6+6O2 ARROW 6CO2+6H2O
you are given the mass of glucose 1.5g
1)convert 1.5g of glucose into moles
1.5g C6H12O6 x 1 mol of C6H12O6
divided by 180g glucose
*the 180g of glucose you get thjem from their atomic mass unit in the periodic table, you add them.
2)in step 1) you get 0.0083molC6H12O6 this multiply it by the # of moles of water H2O that are per each mole of glucose wich is six. so multiply 0.0083 by and you get 0.05 mol H2O.
3)now convert this moles of water to grams of water by multiplyng them by the mass of water, this will give you 0.9g of water and that is the result.

the mass-mole are the smae but without the 3) step

the reaction between X and Y started at 1.00kj and the product of XY was formed at 10.00kj; draw the energy profile for the reaction

In a mass-mole conversion, you are given the mass of a substance and you want to find the number of moles of that substance. This can be done using the formula: moles = mass/molar mass.

Here's an example:
Given the mass of CH4 (methane) is 16 grams, and the molar mass of CH4 is 16 g/mol.
moles = 16g / 16g/mol = 1 mol

In a mass-mass conversion, you are given the mass of one substance and you want to find the mass of another substance in the balanced chemical equation. This can be done using the coefficients in the balanced equation.

Let's take an example:
CH4 + 2O2 → CO2 + 2H2O
We want to find the mass of CO2 when we are given 16 grams of CH4.

1. Convert the given mass of CH4 to moles using the molar mass of CH4 (16 grams/mol) and the formula: moles = mass/molar mass.
moles CH4 = 16g / 16g/mol = 1 mol

2. Use the coefficients in the balanced equation to convert from moles of CH4 to moles of CO2. In this case, 1 mol CH4 is equal to 1 mol CO2 (based on the coefficients in the equation).
moles CO2 = moles CH4 x (1 mol CO2/1 mol CH4) = 1 mol

3. Finally, convert the moles of CO2 to grams of CO2 using the molar mass of CO2 (44 grams/mol).
grams CO2 = moles CO2 x molar mass CO2 = 1 mol x 44g/mol = 44 grams

So, if you have 16 grams of CH4, you will get 44 grams of CO2.

In summary, mass-mole conversions involve converting the mass of a substance to moles using its molar mass, while mass-mass conversions use the coefficients in a balanced chemical equation to convert from the mass of one substance to the mass of another substance. Hope this helps!
