Calculate the molar mass of the compound
3.01x10^23 molecules of compound Z have a mass of 9g
is it
3.01x10^23molescules x 1mol/6.02x10^23 x Z/1mol = 9g
compound Z = 8g
thanks in advance
I wouldn't do it that way.
I would think
3.01 x 10^23/6.02 x 10^23 = 0.5 mol.
So if 0.5 mol has a mass of 9 g, 1 mol would have a mass of ?? grams.
thanks for the correction!
now I have to fix all my answers with the same question format :(
To calculate the molar mass of compound Z, you need to use the given information.
First, you have the number of molecules of compound Z, which is 3.01x10^23. You can convert this to moles using Avogadro's number (6.02x10^23 molecules per mole). Divide the given number of molecules by Avogadro's number:
3.01x10^23 molecules / 6.02x10^23 molecules/mol = 0.5 moles
Next, you have the mass of 0.5 moles of compound Z, which is 9g. Divide the given mass by the number of moles to get the molar mass:
9g / 0.5 mol = 18 g/mol
Therefore, the molar mass of compound Z is 18 g/mol. Note that we do not have enough information to determine the specific identity of compound Z, only its molar mass.
