Calculate the mass of iron(III) oxide that contains a million iron atoms. Be sure your answer has a unit symbol if necessary, an

KiRa [710]

<u>Answer:</u> The mass of iron (II) oxide that contains a million iron atoms is $2.6\times 10^{-17}g$

<u>Explanation:</u>

We are given:

Number of iron atoms = A million = $1.0\times 10^6$

The chemical formula of the given compound is $Fe_2O_3$

It is formed by the combination of 2 iron atoms and 3 oxygen atoms.

According to mole concept:

1 mole of a compound contains $6.022\times 10^{23}$ number of particles

1 mole of iron (II) oxide will contain = $(2\times 6.022\times 10^{23})=1.2044\times 10^{24}$ number of iron atoms

We know that:

Molar mass of iron (II) oxide = 159.7 g/mol

Applying unitary method:

For $1.2044\times 10^{24}$ number of iron atoms, the mass of iron (II) oxide is 159.7 g

So, for $1.0\times 10^6$ number of iron atoms, the mass of iron (II) oxide will be $\frac{159.7}{1.2044\times 10^{24}}\times 1.0\times 10^6=2.6\times 10^{-17}g$

Hence, the mass of iron (II) oxide that contains a million iron atoms is $2.6\times 10^{-17}g$

A gas station charges 1.299 per gallon of gas. What would be the price for a liter of gas?

Fudgin [204]

Answer:

the price for a liter of gas will be of $ 0.3432

Explanation:

⇒ $ gas / L = $ 1.299 / Gal * ( Gal / 3.785 L )

⇒ $ gas / L = $ 0.3432 / L

Convert 2.5 lbs to g

Vesnalui [34]

2.5 * 1/2.2 * 1000 = 1136 g

OR

2.5 * 454 = 1135 g

You can use either for your conversion.

Nitrate salts (NO3), when heated, can produce nitrites (NO2) plus oxygen (O2). A sample of potassium nitrate is heated, and the

Lostsunrise [7]

Answer: a) 0.070 moles of oxygen were produced.

b) New pressure due to the oxygen gas is 2.4 atm

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 2.7 atm

V = Volume of gas = 700 ml = 0.7 L

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = 329 K

$n=\frac{PV}{RT}$

$n=\frac{2.7atm\times 0.7L}{0.0821 L atm/K mol\times 329K}=0.070moles$

Thus 0.070 moles of oxygen were produced.

When the 700 mL flask cools to a temperature of 293K.

$PV=nRT$

$P=\frac{nRT}{V}$

$P=\frac{0.070\times 0.0821\times 293}{0.7}$

$P=2.4atm$

The new pressure due to the oxygen gas is 2.4 atm
