The molar mass of the following compounds in two decimal places are as follows:

NH3: 17.04 g/mol
Mg(OH)2: 58.33 g/mol
Fe2O3: 159.70 g/mol

<h3>MOLAR MASS:</h3>

The molar mass of a compound is the sum of all the atomic masses of the elements that constitutes the compound.

According to this question, three compounds were given as follows: NH3, Mg(OH)2 and Fe2O3.

The atomic mass of the elements in this compounds are as follows:

N = 14
H = 1
Mg = 24
O = 16
Fe = 56

The molar mass of NH3 = 14 + 3 = 17g/mol
The molar mass of Mg(OH)2 = 24 + 32 + 2 = 58g/mol
The molar mass of Fe2O3 = 56(2) + 16(3) = 160g/mol

Determining Molar Mass

Use the periodic table to calculate the molar mass of each of the following compounds. Each answer must have 2 decimal places.

Answer:

- Ammonia ( NH 3 ): 17.04 g/mol is CORRECT :)

- Magnesium hydroxide (MG(OH)2): 58.33 g/mol is CORRECT :)

- Iron (lll) oxide (Fe2O3): 159.70 g/mol is CORRECT :)

A student weighed out a 2.055 g sample of a cobalt chloride hydrate, ConClmpH2O, where n, m, and p are integer values to be dete

topjm [15]

The given mass of cobalt chloride hydrate = 2.055 g

A sample of cobalt chloride hydrate was heated to drive off waters of hydration and the anhydrate was weighed.

The mass of anhydrous cobalt chloride = 1.121 g anhydrate.

The mass of water lost during heating = 2.055 g - 1.121 g = 0.934 g

Converting mass of water of hydration present in the hydrate to moles using molar mass:

Mass of water = 0.934 g

Molar mass of water = 18.0 g/mol

Moles of water = $0.934 g * \frac{1 molH_{2}O }{18 g H_{2}O } =0.0519 mol H_{2}O$

2. Calculate the mass of 3.47x1023 gold atoms.

lapo4ka [179]

3.47 x $10^{23}$ atoms of gold have mass of 113.44 grams.

Explanation:

Data given:

number of atoms of gold = 3.47 x $10^{23}$

mass of the gold in given number of atoms = ?

atomic mass of gold =196.96 grams/mole

Avagadro's number = 6.022 X $10^{23}$

from the relation,

1 mole of element contains 6.022 x $10^{23}$ atoms.

so no of moles of gold given = $\frac{3.47 X 10^{23} }{6.022 X 10^{23} }$

0.57 moles of gold.

from the relation:

number of moles = $\frac{mass}{atomic mass of 1 mole}$

rearranging the equation,

mass = number of moles x atomic mass

mass = 0.57 x 196.96

mass = 113.44 grams

thus, 3.47 x $10^{23}$ atoms of gold have mass of 113.44 grams

Under what conditions is the change in internal energy, δe rxn , equal to the heat evolved in a chemical reaction?

Stells [14]

the first law says that the change in internal energy of a system is given by:

δE = δq + δw

where δE is the i change in internal energy, 

δq is the amount of thermal energy added to the system from the surroundings 

δw is the l work done *on* the system *by* the surroundings. 

For a system only undergoing expansion work,
δw = -pδV, so: 

δE = δq - p δV 
when δV = 0, then δe=δq
