The volume of the ethanol is 6.7 mL
<h3>What is the density of the ethanol?</h3>
We know that density is defined as the ratio of the mass to the volume of an object. We know that the density is said to be an intrinsic property and this means that we can use the density of the object to be able to obtain the kind of object that we are dealing with.
We have the information that the mass of the carbon dioxide that can be obtained from the reaction is about 10 g. We can now use this to obtain the number of moles by the use of the formula;
Number of moles = mass/ molar mass
= 10 g/44 g/mol
= 0.23 moles
From the reaction equation:
1 mole of ethanol produces 2 moles of carbon dioxide
x moles of ethanol produces 0.23 moles of carbon dioxide
x = 0.23 × 1 /2
= 0.115 moles
Mass of ethanol = 0.115 moles × 46 g/mol
= 5.29 g
Volume of the ethanol = mass/density
volume = 5.29 g/0.789 g/mL
= 6.7 mL

Answer:
The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.
Explanation:
As learned above, the amount of air resistance depends upon the speed of the object. ... Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
I think rotation would be the right answer lol
