chegg 2. What pattern did you observe measuring cell voltages with a silver electrode versus with a platinum/H2 electrode There is a difference of -0.786 V in silver
<h3>What is cell voltages ?</h3>
The difference in electric potential between two points, also known as voltage, electric potential difference, electric pressure, or electric tension, is what determines how much labor is required to move a test charge between the two sites in a static electric field. Volt is the name of the derived unit for voltage (potential difference) in the International System of Units. Joules per coulomb, or 1 volt equals 1 joule (of work) for 1 coulomb, is how work per unit charge is stated in SI units (of charge). The quantum Hall and Josephson effect was first employed in the 1990s, and most recently (in 2019), fundamental physical constants have been added for the definition of all SI units and derived units. Power and current were used in the previous SI definition for volt.

Argon, it's a noble gas in the last group on the periodic table.
Hey there!
Sucrose is C₁₂H₂₂O₁₁.
Find molar mass of sucrose:
C: 12 x 12.01 = 144.12
H: 22 x 1.008 = 22.176
O: 16 x 11 = 176
--------------------------------
342.296 grams
That is the mass of one mole of sucrose.
We have 0.0287.
342.296 x 0.0287 = 9.82
The mass of 0.0287 moles of sucrose is 9.82 grams.
Hope this helps!
