Gọi CTHH là HxSyOz
x=\(\dfrac{98.2,04}{100}\approx2\)
y=\(\dfrac{98.36,5}{32.100}\approx1\)
z=\(\dfrac{98.65,03}{16.100}\approx4\)
H2SO4
- CTTQ là HXSyOz
- ta có :
+ x = \(\dfrac{2,04}{100}\) . 98 = 2
+ 32y = \(\dfrac{32,65}{100}\) . 98 = 32 => y = 1
+ 16z = \(\dfrac{65,03}{100}\).98 = 64 => z = 4
- vậy CTHH là H2SO4
