How many grams of CO2 are in 2.52mol of CO2

Chemistry
1 answer:
Thepotemich [5.8K]3 years ago
8 0

Answer:

Mass = 110.88 g

Explanation:

Given data:

Mass of CO₂ = ?

Number of moles of CO₂ = 2.52 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of CO₂  = 44 g/mol

by  putting values,

Mass = 2.52 mol × 44 g/mol

Mass = 110.88 g

Each step in the following process has a yield of 90.0 %. CH 4 + 4 Cl 2 ⟶ CCl 4 + 4 HCl CCl 4 + 2 HF ⟶ CCl 2 F 2 + 2 HCl The CCl
Rainbow [258]

Answer:

4.86 moles of HCl

Explanation:

1. First write the balanced chemical equations involved in the process:

CH_{4}+_4Cl_{2}=CCl_{4}+_4HCl

CCl_{4}+_2HF=CCl_{2}+F_{2}+_2HCl

2. Calculate what amount of CCl_{4} is formed in the first reaction.

3.00molesCH_{4}*\frac{1molCCl_{4}}{1molCH_{4}}=3.00molesCCl_{4}

As the yield of each reaction is 90.0%, the amount of CCl_{4} produced is the following:

3.00molesCCl_{4}*0.90=2.7molesCCl_{4}

3. Calculate the amount of HCl produced.

2.7molesCCl_{4}*\frac{2molHCl}{1molCCl_{4}}=5.4molesHCl

The total amount of HCl produced with a 90.0% yield is:

5.4molesHCl*0.90=4.86molesHCl

A typical hydrogen peroxide solution from a drug store is labeled as 3.0% hydrogen peroxide. What is the other 97% of this compo
GarryVolchara [31]

Answer: Water

Explanation:

Chemically speaking, a solution has two components: solute and solvent.

The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent. </u>

The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used  solvent water.

This means that in a solution there is usually more solvent than solute.

So, in the case of the hydrogen peroxide solution, since the proportion is 3\% to 97\%, the hydrogen peroxide is the solute and water is the solvent.
