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.

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?
There are approximately 0.625 moles of oxygen gas in 40.0 grams. Since the formula for oxygen gas is O2, there are 0.625 moles x 2 = 1.25 moles of oxygen atoms. Therefore, there are approximately 1.25 x 6.022 x 10^23 = 7.53 x 10^23 oxygen atoms in 40.0 grams of oxygen gas.
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.
