The type of solvent that is needed to remove an oil stain would be an organic solvent. This is would dissolve the oil from the fabric to the solvent. Oil is nonpolar which would have the same polarity of an organic solvent. Hope this answers the question. Have a nice day.
Answer:
The mass of 1.26 mole of water, H₂O, is 22.68 grams
Explanation:
Molar mass is the amount of mass that a substance contains in one mole. In other words, the molar mass of an atom or a molecule is the mass of one mole of that particle and its unit is g/mole.
In this case, being:
the molar mass of water H₂O is:
H₂O= 2*1 g/mole + 16 g/mole= 18 g/mole
Then you can apply the following rule of three: if 18 grams are present in 1 mole of H2O, how much mass is present in 1.26 moles of water?
![mass=\frac{1.26 moles*18 grams}{1 mole}](https://tex.z-dn.net/?f=mass%3D%5Cfrac%7B1.26%20moles%2A18%20grams%7D%7B1%20mole%7D)
mass= 22.68 grams
<u><em>The mass of 1.26 mole of water, H₂O, is 22.68 grams</em></u>
