A common liquid contains 11.19% hydrogen and 88.81% oxygen by mass.
a) Calculate the number of moles of hydro- gen atoms and oxygen atoms in 100.0 g of this liquid
b) Calculate the number of hydrogen and oxygen atoms in 100.0 g of this liquid.
(those aren't very important I already solved them)
c) Knowing that the molar mass of this liquid is 18.00 g.mol', calculate how many moles of hydrogen atoms, and how many moles of oxygen atoms are present in a mole of this substance.
d) What is the number of hydrogen and oxy- gen atoms present in one molecule of this substance. Deduce the molecular mass of this liquid and write its molecular formula.​
