0.356 grams of an unknown metal reacts with oxygen to form 452 milligrams of the metal oxide. Identify the metal

Do I assume it forms MO2?

.....2M + O2 ==> 2MO2
..0.356..0.096...0.452
mols O2 = 0.096/32 = 0.003
mols M = 0.003 x 2 = 0.006
molar mass = grams/mol = 0.356/0.006 = 118.7. Look this up on the periodic table.

To identify the metal, we need to determine the molar mass of the metal and the metal oxide formed.

First, let's convert the given masses from grams to moles:
- The mass of the unknown metal is 0.356 grams.
- The mass of the metal oxide is 452 milligrams, which is equal to 0.452 grams.

Next, we can calculate the number of moles for each substance using their respective molar masses:
- Find the molar mass of the metal using the periodic table or any other reliable source.
- Similarly, find the molar mass of the metal oxide by adding up the atomic masses of the metal and the oxygen atoms in the compound.

Finally, we can compare the moles of the metal and the metal oxide to identify the metal. Since the ratios of moles in a chemical reaction are well-defined, we can determine the ratio of moles based on the balanced chemical equation of the reaction.

Given the information in the problem statement, it's not possible to directly identify the metal without further information or assumptions about the balanced equation. Please provide more context, such as the balanced equation or any additional information, to proceed with the identification of the metal.

To identify the metal, we need to calculate the molar mass of the unknown metal and then compare it with the molar masses of different metals till we find a match.

Let's begin by converting the given amounts to moles:

1. Convert 0.356 grams of the unknown metal to moles:
Molar mass of the unknown metal = molar mass of the metal / grams of the metal
Assuming the unknown metal is represented by the symbol "M":
Molar mass of M = 0.356 g / (grams of M)

2. Convert 452 milligrams of the metal oxide to moles:
Since the metal oxide contains oxygen, we need to subtract the molar mass of oxygen from the total molar mass of the metal oxide to find the molar mass of the metal. Assuming the metal oxide is represented by the formula "MO":
Molar mass of M = (452 mg - molar mass of oxygen) / milligrams of M

Now, we can compare the molar masses of different metals until we find a match. The metal with a molar mass that matches the values calculated above will be the identification.

Note: The molar mass of oxygen is 16.00 grams/mole.

By comparing the calculated molar masses with the molar masses of different metals, we can identify the metal that matches the values obtained.
