The empirical formula Of Tin oxide is calculated as follows
Find the mass of oxygen = 0.635 - 0.500 = 0.135
then calculate moles of each element
moles =mass/molar mass
that is Tin(Sn) = 0.500/118.71 = 4.21 x10^-3 moles
for oxygen= 0.135/16= 8.44 x10 ^-3 moles
find the mole ratio by dividing with the smallest mole (4.21 x10^-3)
Sn = ( 4 .21 x10^-3) / (4.21 x10^-3)= 1 mole
O= (8.44 x10^-3 ) /(4.21 x10^-3) = 2 mole
therefore the empirical formula = SnO2
Answer:
9.72 grams.
Explanation:
From the equation, 4 moles of NH₃ produce 6 moles of water.
Therefore the reaction to product ratio of NH₃ to H₂O is 4:6
and 2:3 into its simplest form.
The number of moles of NH₃ in 6.12 g is:
Number of moles=mass/ RMM
=6.12 g/17 G/mol
=0.36 moles.
Therefore the number of moles of H₂O produced is calculated as follows.
(0.36 Moles×3)2 = 0.54 moles
Mass= Number of moles × RMM
=0.54 moles×18g/mol
=9.72 grams.
