An unknown amount of sodium azide (NaN3) reacts and produces 0.033 moles of nitrogen gas. What mass of sodium metal is produced

Chemistry

Monica [59]3 years ago
3 0

Answer:

Mass of sodium metal is 130.87 gram

Explanation:

The complete reaction is

2 NaN3 --> 2 Na + 3 N2

We know that PV = nRT

n = \frac{PV}{RT}

On substituting the given values, we get

n = \frac{\frac{99707}{101325}*75 }{0.082 *(273.15 +15)} \\n = 3.02moles of N2

Sodium azide's molar mass

3.02 *(2/3) = 2.013 moles

Mass = 2.03 * 65.01 = 130.87 gram

How is stoichiometry used to calculate the amount of product from amount of reactant?
IceJOKER [234]
<span>Stoichiometry deals with the quantitative measurement of reactants and products in a chemical reaction. Let suppose you are given with following reaction;

                                            A  +  2 B   </span>→    3 C

According to this reaction 1 mole of A reacts with 2 moles of B to produce 3 moles of C. Now using the concept of mole one can easily measure the amount of reactants reacted and the amount of product formed, as...

                    1 Mole Exactly equals 6.022 × 10²³ particles

                    1 Mole of Gas (at STP) exactly occupies 22.4 L Volume

                    1 Mole of any compound exactly equals the molar mass in                                 grams

Therefore, <span>Stoichiometry is very helpful in quantitative analysis.</span>

What is the molarity of 60.0 grams of NaOH dissolved in 750 milliliters of water?
Bumek [7]

<u>Answer:</u>

The correct answer option is B) 2.0 M.

<u>Explanation:</u>

We are given the number of grams of NaOH (Sodium Chloride) which are dissolved in 750 milliliters of water and we are to find its molarity.

We know the formula of molarity:

<em>Molarity =  (mass * 1000) / (volume * molecular mass)  </em>

Volume = 750 ml = 750 cm^3

Molecular mass = 40  

Mass = 60 grams

Substituting these values in the above formula:

Molarity = \frac{(60*1000)}{750*40} = 2.0 M

If 20 grams of N2 react completely with H2 , how many moles of NH3 are produced? Show Work
Maslowich
This is the balanced eq
N2 + 3H2 -> 2NH3
first you need to find mole of N2 by using
mol = mass ÷ molar mass.
mol N2= 20g ÷ (14.01×2)g/mol
=0.7138mol
then look at the coefficient between H2 and NH3.
it is N2:NH3
1:2
0.7138:0.7138×2
0.7138:1.4276 moles
moles of NH3 = 1.4276 moles
