How many moles are in 6.5g of carbonate​

Chemistry
1 answer:
NikAS [45]3 years ago
3 0

Answer:

Number of moles =  0.12 mol

Explanation:

Given data:

Mass of carbonate = 6.5 g

Moles of carbonate = ?

Solution:

Number of moles = mass / molar mass

Molar mass of carbonate = 60 g/mol

Now we will put the values in formula:

Number of moles = 6.5 g/ 60 g/mol

Number of moles = 0.12 mol

What is the basic definition of carbohydrates
ikadub [295]

Carbohydrates are substances that are found in foods such as bread and pasta, which provide the body with heat and energy. Chemically, carbohydrates are made of three kinds of elements namely carbon , hydrogen and oxygen.

Carbohydrates are separated into two main categories, simple carbohydrates and complex carbohydrates.  

Simple carbohydrates are those that contain one or two sugar molecules linked together. Complex carbohydrates are those that contain  three or more sugar molecules linked together. In some cases these chains can contain hundreds of sugar molecules.

A method used by the U.S. Environmental Protection Agency (EPA) for determining the concentration of ozone in air is to pass the
baherus [9]

Answer: 1. 9.08\times 10^{-6} moles

2. 90 mg

Explanation:

O_3(g)+2NaI(aq)+H_2O(l) \rightarrow O_2(g)+I_2(s)+2NaOH(aq)

According to stoichiometry:

1 mole of ozone is removed by 2 moles of sodium iodide.

Thus 4.54 \times 10^{-6} moles of ozone is removed by =\frac{2}{1}\times 4.54 \times 10^{-6}=9.08\times 10^{-6} moles of sodium iodide.

Thus 9.08\times 10^{-6} moles of sodium iodide are needed to remove 4.54\times 10^{-6} moles of O_3

2. \text{Number of moles of ozone}=\frac{0.01331g}{48g/mol}=0.0003moles

According to stoichiometry:

1 mole of ozone is removed by 2 moles of sodium iodide.

Thus 0.0003 moles of ozone is removed by =\frac{2}{1}\times 0.0003=0.0006 moles of sodium iodide.

Mass of sodium iodide= moles\times {\text {molar mass}}=0.0006\times 150g/mol=0.09g=90mg    (1g=1000mg)

Thus 90 mg of sodium iodide are needed to remove 13.31 mg of O_3.
