Question

110 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.

Answer 1

Step-by-step explanation:

number of moles =

`(given \: mass)/(molar \: mass)`

thus, number of moles of hydrogen= 11.91/1

=> 11.91

number of moles of oxygen= 88.81/32 = 2.77

=> 2.77

hope it helps:)
