How many oxygen atoms in 0.800 moles MgO?
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
How many moles of carbon dioxide are there in 800 cm3 of gas at 30 C and 110 kPa?
0.035mol. Apply to PV=nRT
How many grams of oxygen will be required to produce 25 moles of sulfur dioxide how many grams of oxygen will be required to produce 25 moles of sulfur dioxide?
800 g oxygen are needed.
how many hydrogen atoms are in 800 grams of C3H8?
So, there are approximately 8.74 × 1 0 24 8.74×10 24 hydrogen atoms in 800 grams of C 3 H 8 C 3 H 8 .
25 moles of sulfur dioxide how many grams of oxygen does it contain?
25 moles of sulfur dioxide contain 600 grams of oxygen. Each mole of SO2 contains 2 moles of oxygen, and the molar mass of O is 16 g/mol. So, 25 moles x 2 moles = 50 moles of O, which is 50 moles x 16 g/mol = 800 g of O.
How many atoms would remain of Au-198 that has 800 atoms after 8.1 days if its half-life is 2.7 days?
After 8.1 days, three half-lives have passed for Au-198 (2.7 days/half-life * 3 half-lives = 8.1 days). Each half-life reduces the number of atoms by half, so remaining atoms = 800 atoms * (1/2)^3 = 100 atoms.
How many 25 ¢ is in $800?
How many 25¢ is in $800
What happens to a diamond in an 800 degree oven?
Diamonds are pure carbon, a useful form of clean burning fuel. In an 800 degree oven, and an oxygen atmosphere, the diamond burns cleanly and turns into Carbon Dioxide gas. Its an expensive way to heat your house. +++ LOL! Carbon is certainly a very useful fuel in its more common though artificially-modified versions (coke and charcoal), but certainly not in its diamond form!
How many millions is 800 million?
There are 800 millions in 800 million.
How many ml are in 800?
800mL equals 80cL
how many times does 800 go into 640,000?
It goes in 800 times.
The half-life of Au-198 is 2.7 days When there are 800 atoms of Au-198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8.1 days how many atoms of Au-198 remaining?
After 8.1 days, three half-lives have passed (8.1 days / 2.7 days = 3). With each half-life, the number of atoms is halved. Therefore, starting with 800 atoms, after three half-lives there would be 800 / 2 / 2 / 2 = 100 atoms remaining.
