2.07 mol of [tex]CH_4[/tex] and 0.766 mol of [tex]H_2O[/tex] are contained in each of the following.
What is a mole?
A mole is a very important unit of measurement that chemists use. A mole of something means you have 602,214,076,000,000,000,000,000 of that thing, like how having a dozen eggs means you have twelve eggs.
33.3g of [tex]CH_4[/tex]
Molecular mass of [tex]CH_4[/tex] = 16.04 g/mol
Moles = [tex]\frac{mass}{molar \;mass}[/tex]
Moles = [tex]\frac{33.3g}{16.04 g/mol}[/tex]
Moles = 2.07 mol
13.8g of [tex]H_2O[/tex]
The molecular mass of [tex]H_2O[/tex]= 18.01528 g/mol
Moles = [tex]\frac{mass}{molar \;mass}[/tex]
Moles = [tex]\frac{13.8g }{18.01528 g/mol}[/tex]
Moles = 0.766 mol
Hence, 2.07 mol of [tex]CH_4[/tex] and 0.766 mol of [tex]H_2O[/tex] are contained in each of the following.
