Answer 2

You have t convert to moles first. After that, divide each value by the smallest value that was calculated when converting. Round and use that to determine the empirical formula.

Answer 3

can you help me solve it

Answer 4

The only formula you need is: \(\sf moles=\dfrac{mass}{Molar~mass}\)

for example, for hydrogen, \(\sf moles_H=\dfrac{mass_H}{Molar~mass_H}=\dfrac{22~g}{1.008~g/mol}\approx 22~moles \)
