Answer:
19.28 g/cm^3 to the nearest hundredth.
Explanation:
The volume of water displaced = the volume of the metal.
density = mass / volume
0.0694 kg = 0.0694 * 1000
= 69.4 g.
Density = 69.4 / 3.6
= 19.28 g/cm^3.
Answer:
C. An external voltage source
Explanation:
An electrolytic cell converts electrical energy from an external voltage source into chemical energy that drives a reaction.
The external voltage source is usually a battery. This energy form generated from the battery helps to drive chemical reactions.
The process involves the decomposition of an ionic compound by means of current passed into the aqueous or molten form of the compound through conductors known as electrodes.
The "Ideal Gas Law Equations" is

P= Pressure (in Pascals)
V=Volume (in Liters)
n=amount, or <u>
n</u>umber (in moles)
R= 8.3145

or

T= Temperature (In Kelvin)

Plug into the equation and you're good!



If your teacher cares about sig figs,
2 sig figs (significant figures)

For other units of pressure,
1 atm = 760 mmHG = 760 Torr = 101326 Pa = 1.01325 bar<u />
