How many moles in 1 teaspoon of sand , chalk , sugar

Chemistry
1 answer:
Monica [59]3 years ago
6 0
In order to calculate for the number of moles of these substances, we have to know what are chemical formulas of these and their molar masses. They are as follows:

sand = SiO2 (60.08 g/mol)
chalk = CaCO3 (100.0869 g/mol)<span>
sugar = C12H22O11 (</span>342.2965 g/mol)

The commonly used conversion would be that 1 teaspoon is equal to approximately 5 grams. We calculate as follows:

sand = 5 / (60.08 g/mol) = 0.08 mol
chalk =5 / (100.0869 g/mol) = 0.05 mol
sugar = 5 / (342.2965 g/mol) = 0.01 mol

Determine the amount in grams of kcl that exists in 20.3 g of a solution that contains 1.14 % KCI by mass.
artcher [175]

Answer:

0.23 g

Explanation:

From the question given above, the following data were obtained:

Mass of solution = 20.3 g

Percentage by mass of KCl = 1.14%

Mass of KCl =?

The mass of KCl in the solution can be obtained as follow:

Percentage by mass = mass of solute / mass of solution × 100

1.14% = mass of KCl / 20.3

Cross multiply

Mass of KCl = 1.14% × 20.3

Mass of KCl = 1.14/100 × 20.3

Mass of KCl = 0.0114 × 20.3

Mass of KCl = 0.23 g

Therefore, the mass of KCl in the solution is 0.23 g

Melting is an endothermic process. Using the terms 'kinetic energy' and 'intermolecular forces', explain how the addition of ene
Helen [10]

Melting is a process where a solid such as ice turns into liquid or water. The molecules of ice slowly moves and becomes unstable as they gain energy. As this energy builds up, kinetic energy increases and the intermolecular forces react because of this energy.Thank you for your question. Please don't hesitate to ask in Brainly your queries.

How many moles of H₂O are produced from 3 moles of oxygen
BabaBlast [244]

Answer:

6 mols

Explanation:

Notice that on the left, there is one "O2" molecule, and one O2 results in two "H2O" molecules. So the ratio of O2 to H2O is 1 to 2
If we have 3 mols of oxygen, then per the ratio, we would have 6 mols of H2O, since 3*2=6
