Calculate the mass in grams of 2.56x10 -3 mol of iron.

Answers

Final answer:

The mass in grams of 2.56x10-3 mol of iron is 0.143 g.

Explanation:

To calculate the mass in grams of 2.56x10-3 mol of iron, you need to use the molar mass of iron. The molar mass of iron is 55.845 g/mol. To find the mass in grams, you can use the following step-by-step calculation:

Mass (g) = Number of moles x Molar mass

Mass (g) = 2.56x10-3 mol x 55.845 g/mol = 0.143 g

A solid compound in a sealed container was kept at a very low temperature in a freezer. When placed at room temperature, the substance quickly turned into a liquid. This compound is most likely which of the following?a.an ionic compound because it has a low boiling point
b. a covalent compound because it has a low boiling point
c.an ionic compound because it has a low melting point
d.a covalent compound because it has a low melting point

Answers

Answer: A solid compound in a sealed container is a covalent compound because it has a low melting point.

Explanation:

Ionic compounds have strong electrostatic forces which are strong in nature and cannot be broken down at low temperature.

Whereas covalent compounds have Vanderwaal forces which are weak in nature. Therefore, covalent compounds melts at low temperature.

Thus, it can be concluded that a solid compound in a sealed container is a covalent compound because it has a low melting point.
