Chemistry

SVETLANKA909090 [29]3 years ago
3 0

Answer:

56.24g

Explanation:

To find the mass of N2O3 in 4.45 x 10^23 molecules, it must first be converted to moles by dividing the number of molecules in N2O3 by Avagadro's number (6.02 × 10^23).

number of moles in N2O3 = 4.45 x 10^23 ÷ 6.02 × 10^23

n = 4.45/6.02 × 10^(23 - 23)

n = 0.74 × 10^0

n = 0.74moles.

Using the formula below to find the mass of N2O3;

mole = mass ÷ molar mass

Molar mass of N2O3 = 14(2) + 16(3)

= 28 + 48

= 76g/mol

mass = mole × molar mass

Mass = 0.74 × 76

Mass = 56.24g

Which statement defines reduction potential when considering a pair of half-cell reactions?
torisob [31]
Reduction is the gain of electrons, then potential of reducción is the tendency of a sustance to gain electrons. In this case the sustance is an electrode.

Then the reduction potential refers to the tendency of one electrode to gain electrons and it is measured against a standard electrode which is the electrode of hydorgen.

When you consider the pair of half-cell reactions, the potential of the cell is the reduction potential - oxidation potential.

How many moles are there in 2.00 x 1023 molecules of LiOH?​
Tanya [424]

Answer:

Moles de LiOH= 0.33212 Moles

Explanation:

1 Mol of LiOH -->6.022*10^23 molecules of LiOH

therefore

2*10^{23}~molecules ~of~LiOH=\frac{2*10^{23}}{6.02*10^{23}}Moles~of#LiOH
