What is the difference between mole ratios and volume ratios?

Volume ratio works the same way as the mole ratio (explanation is in the gas laws i think)

mole ratio 1:2

1 mole compound A, you need two moles of compound B

Volume ratio 1:2

150 ml compound A, 300 mL compound B

CORRECT ME IF IM WRONG BUT I THINK IT WORKS IN THE SAME WAY!

What is the difference between mole ratios and volume ratios?
Mole Ratio:
Basically a ratio of the moles of 1 element or compound with another,
e.g. In 2H2 + O2 -> 2H2O, the mole ratio of H2 to O2 is 2:1 (coefficients are treated as moles).

Volume Ratio:
Have only really seen this being referred to when gases react. When gases react at standard lab conditions (101kPa and 25 degrees) the coefficients of the gases within the reactions can be treated as the volumes of the gases.

e.g. for the reaction above used in the mole ratio explanation assume water is in its gaseous state. Thus, the ratio of hydrogen to oxygen to water vapour is 2mL:1mL:2mL
