# How many grams of Na(l) are produced per litre of N2(g) formed in the decomposition of sodium azide, NaN3 if the gas is collected at 25 degrees celsius and 1.0 bar (.98692 atm)? The R constant is 0.08206 Latm/Kmol

##### 1 Answer

The reaction produces

#### Explanation:

We aren’t given the amount of

There are six steps involved in this problem:

- Write the
**balanced equation**for the reaction. - Use the
**molar ratio**of#"Na":"NaN"_3# from the balanced equation to calculate the moles of#"Na"# . - Use the molar mass of
#"Na"# to calculate the mass of#"Na"# . - Use the
**molar ratio**of#"N"_2:"NaN"_3# from the balanced equation to calculate the moles of#"N"_2# . - Use the
**Ideal Gas Law**to calculate the volume of#"N"_2# . - Calculate the mass of
#"Na"# per litre of#"N"_2# .

Let's get started.

**Step 1. Write the balanced chemical equation.**

**2. Calculate the moles of #"Na"#**

**3. Calculate the mass of #"Na"#.**

**4. Calculate the moles of #"N"_2#.**

**5. Calculate the volume of #"N"_2#.**

The **Ideal Gas Law** is

#color(blue)(|bar(ul(PV = nRT)|)#

We can rearrange the Ideal Gas Law to get:

**5. Calculate the #"Na:N"_2# ratio.**
