How many moles are in 1 gram of magnesium?

Each atom has a different size and therefore a different mass. The relative masses of each element can be found on the periodic table. For example, one atom of magnesium weighs 24.31 amu (atomic mass units). However, one mole of magnesium weighs 24.31 g.

How do you calculate moles of magnesium?

Example calculation:

  1. Mass magnesium = 2.39 g.
  2. Mass magnesium oxide = 3.78 g.
  3. So mass oxygen = 1.39 g.
  4. Number moles Mg = 2.39/24 = 0.0995.
  5. Number moles O = 1.39/16 = 0.0868.
  6. Divide by the smallest to give the ratio aproximately 1 Mg : 1 O.
  7. This would suggest a formula of MgO, which is the correct formula.

How many moles are in 10 grams of oxygen?

Hence, there are 0.3125 moles of oxygen are present in 10 g of oxygen gas.

How many atoms are in 12 grams of magnesium?

So, in 12g of Mg, there is 0.5 moles of Mg present, which translates to roughly 3.01 x 10^23 atoms.

How many moles are there in 48 grams of magnesium?

Now, coming back to the formula to find the number of atoms. Therefore, number of atoms in 48 g of Mg = 2 mol $ \times $ $6.022 \times {10^{23}}$atoms/mol= \[12.04 \times {10^{23}}\] atoms. Thus, 48 g of Mg is equivalent to $12.04 \times {10^{23}}$ atoms.

How many moles are there in 24 grams of magnesium?

Thus, for any given amount of an element number of corresponding moles can be found using unitary method. From the above information, $\frac{{12}}{{24}} = 0.5$ moles of magnesium are present in magnesium ribbon. We can do it also in an alternative method. i.e.

How many moles are in MgO?

To find the molar quantity, we simply divide the mass by the molar quantity, to get an answer in moles : Moles of MgO = 42.5⋅g 40.3⋅g ⋅mol−1=1.05⋅mol .

How many atoms are there in 10 grams of oxygen?

Atomic mass O is 15.9994. Molar mass of O2 =2 X 15.9994=31.99880 g/mole. 188194557295898596197357 atoms in 10 grams O2.

How many molecules are in 10 grams of O2?

There are 1.51×1023molecules O2 in 10.0 g O2 .
