A 32.0-g sample of HF is dissolved in water to give 2.0 × 102 mL of solution. The concentration of the solution is:
guajiro [1.7K]

 The concentration of the  solution is  8 M


 <u><em>calculation</em></u>

<em>  </em>Concentrati<em>on   =  moles/volume  in liters</em>

<em>  </em><em>step 1: find moles of HF</em>

<em>moles  of HF  =mass/molar mass</em>

<em>molar mass of  HF =  1+  19 )= 20 g/mol</em>

<em> moles is  therefore = 32.0  g/ 20 g/mol= 1.6  moles</em>

<em>Step 2:  convert  ml to L</em>

<em>volume in liters = 2.0 x 10^2 / 1000 =0.2 l</em>

<em>step 3: find the concentration</em>

<em>concentration  =  1.6 mol  / 0.2 l = </em><em>8 M</em>

What mass of hydrogen will be produced by the reaction of 67.3 g of tin with excess water according to the following reaction?
Crank

Answer:

Mass of hydrogen produced =2.28 g

Explanation:

Given data:

Mass of tin = 67.3 g

Mass of hydrogen produced = ?

Solution:

Chemical equation:

Sn + 2H₂O    → SnO₂+ 2H₂

Number of moles of Sn:

Number of moles = mass/ molar mass

Number of moles = 67.3 g/ 118.71 g/mol

Number of moles = 0.57 mol

Now we will compare the moles of tin with hydrogen from balance chemical equation.

                             Sn             :               H₂

                              1               :                2

                          0.57             :               2×0.57 = 1.14

Mass of hydrogen:

Mass = number of moles ×molar mass

Mass = 1.14 mol × 2 g/mol

Mass = 2.28 g
