Answer:
B) 1
Explanation:
Lithium is a univalent element, univalent means that it has only one valence electron. If this is true, then lithium can only provide this one valence electron in a voltaic cell.
From the foregoing, each lithium atom can only provide one valence electron in the voltaic cell.

Chemical Formula is not a chemical name. It is a way of showing details or
information about the proportion of atoms that compose a certain chemical
compound, using a single line of chemical element symbols, numbers,
and sometimes also other symbols, such as dashes, parentheses, commas, plus
(+) and minus (-). </span>

1 mole Cu ------------------ 6.02x10²³ atoms
0.90 moles Cu ------------ ??
0.90 x ( 6.02x10²³ ) / 1 =
= 5.41x10²³ atoms
Hello!
A 250 mL sample of a 0,125 M solution of NaOH contains
1,25 g of NaOH
To calculate that, we use the definition of molar concentration (M=moles/L) and the solution volume in L to get the moles of NaOH in the solution. After that, we get the mass of NaOH from the molar mass. All these calculations are shown in the following conversion factor:
