If an insufficient amount of liquid unknown had been used, how would this have effected the value of the experimental molar mass
Effectus [21]
<span>When the unknown liquid is heated and turned into vapor, it will not occupy the entire container. The volume in the molar mass (nRT)/PV will be greater than the actually volume of the unknown, and the calculated molar mass will be less than the actual molar mass.</span>

When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water according to the r
Lynna [10]

Answer:

54.0 g.

Explanation:

  • From the given data and the balanced reaction:

<em>2H₂ + O₂ → 2H₂O.</em>

<em></em>

When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water according to the balanced reaction.

<em>∴ The no. of grams in 3.0 moles of water = no. of moles x molar mass </em>= (3.0 mol)(18.0 g/mol) = <em>54.0 g.</em>

what is the mass (in grams) of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride?
Gnoma [55]

The mass of chlorine required to react with 10.0 g of sodium metal to produce sodium chloride is 15.26 g.

The balanced chemical reaction is :

<em>            2Na + Cl₂ → 2NaCl</em>

<em />

Given data :

Mass of sodium = 10.0 g

Number of moles of Na -

Number of moles = <u>  Given mass  </u>

                                    Molar mass

Number of moles = <u> 10.0 g</u> = 0.43 mol

                                  23 g

Comparing moles of Na and Cl₂ from the balanced chemical equation,

                                            Na        :        Cl₂

                                             2          :         1

                                             0.43     :        <u> 1 </u> x 0.43 = 0.215 mol

                                                                   2

Mass of chlorine gas :

          (molar mass of chlorine = 71 g)

Mass of chlorine = number of moles x molar mass

Mass = 0.215 mol x 71 g/mol

          = 15.26 g
