What is X squared times negative x squared?
If you mean -(x^2) * x then the answer is -x^3 if you mean (-x)^2 * x then the answer is x^3
Formula of mean absolute deviation?
Mean absolute deviation = sum[|x-mean(x)|]/n Where mean(x) = sum(x)/n and n is the number of observations. |y| denotes the absolute value of y.
X plus 6 divided by x?
This question is ambigous. If you mean (x+6)/x then it simplifies to 1 + (6/x) If you mean x + (6/x) then it can't really be simplified.
What does the X mean in?
The "x" means unknown.

How many individual oxygen atoms are present in 20 moles of oxygen gas?
20 x 2 x 6.022x1023 = 2.409x1025 atoms of oxygen
What is the balance the following chemical equation Al2O3 -- Al plus O2?
No. If you mean 4Al3O2. And If you mean 4Al + 3O2 ------> AL2O, it is still not balance.
How many oxygen molecules are there in in 4 g of oxygen?
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
How many molecules in oxygen gas?
There are 1/6.022 x 1023 = 1.66 x 10-24 moles of oxygen in 1 molecule of O2.
24.8g of oxygen contains ______.a. 9.33 x 10^23 oxygen atomsb. 50 amuc. none of thesed. 1.49 x 10^25 oxygen moleculese. 1.55 mol of oxygen molecules?

What is the number of oxygen atoms present in 4.0g of oxygen?
The molar mass of oxygen is 16.0 g/mol. Therefore, in 4.0g of oxygen, there are 4.0/16.0 = 0.25 moles of oxygen. Since each mole of oxygen contains 6.022 x 10^23 atoms, there are 0.25 x 6.022 x 10^23 = 1.5055 x 10^23 oxygen atoms present in 4.0g of oxygen.
What does the name oxygen in German mean?
oxygen = Sauerstoff
How many oxygen atoms are present in 40.0 grams of oxygen gas?
Ar of O = 16g/mol Mr of O2 = 2(16) = 32g/mol Using the formula : Number of moles = mass / Mr Number of moles = 40g / 32g/mol = 1.25mols One mole of substance contains the same number of particles as the Avogadro constant, which is 6.02 x 10^23 Number of Oxygen molecules = 1.25 x 6.02 x 10^23 = 7.525 x 10^23 Each Oxygen molecules contain two Oxygen atoms Number of Oxygen atoms = 7.525 x 10^23 = 1.505 x 10^24 atoms
Why doesnt air have a chemical symbol?
because air is also known as OXYGEN IN A SCIENCY WAY X oxygen is known simply as ''O'' i think because air is also known as OXYGEN IN A SCIENCY WAY X oxygen is known simply as ''O'' i think because air is also known as OXYGEN IN A SCIENCY WAY X oxygen is known simply as ''O'' i think
1.2 moles of oxygen atoms represent?
1.2 moles of oxygen atoms represent approximately 7.2 x 10^23 oxygen atoms. This is because 1 mole of any element contains Avogadro's number (6.022 x 10^23) of atoms. So, 1.2 moles would contain 1.2 times Avogadro's number of oxygen atoms.
How many atoms are present in 16g og Oxygen?
One mole of oxygen has a mass of 16 grams and contains 6.022 x 10^23 oxygen atoms. Therefore, 16 grams of oxygen will also contain 6.022 x 10^23 oxygen atoms.
How many atoms of oxygen are contained in each what How many oxygen atoms in 21 g of O2 How many oxygen atoms in 0.812 moles MgO How many oxygen atoms in 3.2 x 1022 molecules of C6H12O6?
a. number of atoms = mass / molar mass x avagadros number 21/16x6.02x1023=7.9x1023 atoms b. number of atoms = moles x avagadros number 0.812x6.02x1023=4.89x1023 atoms as there is 1 O atom in each molecule of MgO, there are 4.89x1023 atoms of Oxygen. c. if there are 3.2x1022 molecules and 6 oxygen atoms in each molecule then: (3.2x1022)x6=1.92x1023 Oxygen atoms.
