Asolution has a volume of 2.0 l and contains 36.0 grams of glucose (c6h12o6). if the molar mass of glucose is 180 g/mol, what is the molarity of the solution?

36.0 g of glucose divided by 180 g/mol = 0.200 moles of glucose 

find molarity
0.200 moles of glucose / 2 liters = 0.100 molar solution 

(hope this helps)

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
