Explain the term conservation of mass

emmasim [6.3K]

The term conservation of mass means that mass in any system can neither be created nor destroyed but can be transformed from one state to another.

<h3>What is the law of mass of conservation?</h3>

The law of conservation states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.

This means that when an element is involved in a chemical reaction, it's mass remains the same at the end of that reaction.

Answer: 4.74 moles

Explanation:

$2LiBr+Ba\rightarrow BaBr_2+2Li$

Moles of Ba= $\frac{\text {given mass}}{\text {molar mass}}$

Moles of Ba= $\frac{325g}{137g/mol}=2.37 moles$

According to given balanced equation,

1 mole of Barium gives 2 moles of Li

Thus 2.37 moles of Barium gives= $\frac{2}{1}\times 2.37=4.74 moles$

Thus 4.74 moles of lithium will be produced by 135 g of barium.

Nitroglycerine decomposes violently according to the chemical equation below. What mass of carbon dioxide gas is produced from t

AveGali [126]

Answer : The mass of $CO_2$ produced is, 7.74 grams

Solution : Given,

Mass of $C_3H_5(NO_3)_3$ = 13.3 g

Molar mass of $C_3H_5(NO_3)_3$ = 227 g/mole

Molar mass of $CO_2$ = 44 g/mole

First we have to calculate the moles of $C_3H_5(NO_3)_3$ .

$\text{ Moles of }C_3H_5(NO_3)_3=\frac{\text{ Mass of }C_3H_5(NO_3)_3}{\text{ Molar mass of }C_3H_5(NO_3)_3}=\frac{13.3g}{227g/mole}=0.0586moles$

Now we have to calculate the moles of $CO_2$

The balanced chemical reaction is,

$4C_3H_5(NO_3)_3\rightarrow 12CO_2(g)+6N_2(g)+10H_2O(g)+O_2(g)$

From the reaction, we conclude that

As, 4 mole of $C_3H_5(NO_3)_3$ react to give 12 mole of $CO_2$

So, 0.0586 moles of $C_3H_5(NO_3)_3$ react to give $0.0586\times \frac{12}{4}=0.176$ moles of $CO_2$

Now we have to calculate the mass of $CO_2$

$\text{ Mass of }CO_2=\text{ Moles of }CO_2\times \text{ Molar mass of }CO_2$

$\text{ Mass of }CO_2=(0.176moles)\times (44g/mole)=7.74g$

Thus, the mass of $CO_2$ produced is, 7.74 grams
