Answer:

99.3%

Explanation:

The percent by mass of the solute can be expressed as:

  • % mass = \frac{MassSolute}{MassSolute+MassSolvent} * 100%

And for this problem:

  • Mass of Solute = Mass of sodium lithium chloride = 29 g
  • Mass of Solvent = Mass of Water

So to calculate the percent by mass first we need to <u>calculate the mass of water</u>, to do so we use its<em> density</em> (1 g/L):

  • 202 mL is equal to (202/1000) 0.202 L.

Density water = mass water / volume

  • 1 g/L = mass water / 0.202 L
  • Mass water = 0.202 g

Now we have all the data required to <u>calculate the % mass:</u>

  • % mass = \frac{29g}{29g+0.202g} * 100 % = 99.3%

Hydrogenation reactions, in which H2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer indu
ddd [48]

<u>Answer:</u> The amount of heat released is 56 MJ.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}  

Given mass of C_2H_6 = 12 kg = 12000 g    (Conversion factor: 1 kg = 1000 g)

Molar mass of C_2H_6 = 30 g/mol

Putting values in above equation, we get:

\text{Moles of }C_2H_6=\frac{12000g}{30g/mol}=400mol

The chemical reaction for hydrogenation of ethene follows the equation:

C_2H_4+H_2\rightarrow C_2H_6

By Stoichiometry of the reaction:

When 1 mole of ethane releases 140 kJ of heat.

So, 400 moles of ethane will release = \frac{140}{1}\times 400=56000kJ of heat.

Converting this into Mega joules, using the conversion factor:

1 MJ = 1000 kJ

So, \Rightarrow 56000kJ\times (\frac{1MJ}{1000kJ})=56MJ

Hence, the amount of heat released is 56 MJ.
