The density of the liquid is 0.98 g/mL
<h3>What is density? </h3>
The density of a substance is defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as:
Density = mass / volume
With the above formula, we can obtain the density of the liquid.
<h3>How to determine the density </h3>
- Mass = 30.8 g
- Volume = 31.5 mL
- Density =?
Density = mass / volume
Density of liquid = 30.8 / 31.5
Density of liquid = 0.98 g/mL

I think that marijuana should be legalized for recreational use. It's not really bad for you and it doesn't cause problems like violence. If marijuana was the most abused substance rather than alcohol it would be an improvement.
Answer:
11.5moles of oxygen gas
Explanation:
The reaction equation is shown below;
C₂H₆O + 3O₂ → 2CO₂ + 3H₂O
We were given 11.5moles of H₂O produced;
Since the equation is balanced;
3 mole of oxygen gas was used to produce 3 mole of water
11.5 moles of water will be produced 
= 11.5moles of oxygen gas
A galvanic cell is formed when two metals are immersed in solutions differing in concentration 1 when two different metals are immersed.
<h3>What is galvanic cell?</h3>
A galvanic cell is an electrochemical device that transforms chemically generated free energy into electrical energy. A photogalvanic cell produces photochemical species that react to produce an electrical current when connected to an external circuit.
<h3>How does galvanic cell works?</h3>
In order to create a pathway for the flow of electrons via this wire, the galvanic cell makes use of the ability to split the flow of electrons during the processes of oxidation and reduction, forcing a half-reaction and linking each with a wire.
An electrochemical device known as a galvanic cell converts chemical energy from a spontaneous redox response into electrical energy. It possesses an electrical potential of 1.1 V. The anode, which is a negative plate in galvanic cells, is where oxidation takes place. It is a positive plate where lessening takes place.
