how many atoms of oxygen are contained in 0.662 mol of magnesium carbonate?
MgCO3.
There are 6.02E23 molecules of MgCO3 in 1 mole MgCO3 and since there are 3 atoms O per 1 molecule of MgCO3, there will 3x that number of O atoms.
To determine the number of oxygen atoms in 0.662 mol of magnesium carbonate, we need to consider the chemical formula of magnesium carbonate and use Avogadro's number.
The chemical formula of magnesium carbonate is MgCO3. From this formula, we can see that there is one oxygen atom in each molecule of magnesium carbonate.
Avogadro's number states that one mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, or formula units).
To find the number of oxygen atoms in 0.662 mol of magnesium carbonate, we can use the following formula:
Number of oxygen atoms = Number of moles of magnesium carbonate * Avogadro's number
Number of oxygen atoms = 0.662 mol * 6.022 x 10^23 atoms/mol
Calculating this, we have:
Number of oxygen atoms = 3.981 x 10^23 atoms
Therefore, there are approximately 3.981 x 10^23 oxygen atoms in 0.662 mol of magnesium carbonate.
To find the number of atoms of oxygen in 0.662 mol of magnesium carbonate, we need to know the chemical formula of magnesium carbonate (MgCO3).
In magnesium carbonate, there is one atom of magnesium (Mg), one atom of carbon (C), and three atoms of oxygen (O).
The molar ratio between magnesium carbonate and oxygen is 1:3. This means that for every one mole of magnesium carbonate, there are three moles of oxygen.
First, we need to convert the given amount of magnesium carbonate (0.662 mol) to moles of oxygen.
Moles of oxygen = moles of magnesium carbonate × (3 moles of oxygen / 1 mole of magnesium carbonate)
Moles of oxygen = 0.662 mol × 3 = 1.986 mol
To find the number of atoms, we multiply the moles of oxygen by Avogadro's number, which is approximately 6.022 × 10^23.
Number of atoms of oxygen = moles of oxygen × Avogadro's number
Number of atoms of oxygen = 1.986 mol × 6.022 × 10^23 = 1.195 × 10^24 atoms of oxygen
Therefore, there are approximately 1.195 × 10^24 atoms of oxygen in 0.662 mol of magnesium carbonate.
