The independent variable would be the dry ice being placed in the water/other liquid (D) and the dependent variable would be the water/other liquid the dry ice (ID) is being placed in.
If 100cm is 1 metre
Then 0.57 cm =
If less more divides,
Hence 100÷0.57 × 1
= 0.0057 Metres.
Because their molecules are more tightly packed. Massdensity = ---------- Volume
So more densely packed molecules means more mass per unit volume. Hence metals are denser than non-metals.
Answer : The number of moles of oxygen needed are, 1.5 moles.
Explanation :
The balanced chemical reaction will be:

Now we have to calculate the moles of oxygen.
From the balanced chemical reaction we conclude that,
As, 6 moles of water vapor produces from 5 moles of oxygen
So, 1.80 moles of water vapor produces from
moles of oxygen
Therefore, the number of moles of oxygen needed are, 1.5 moles.
