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 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.

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.
How many passanger in Boeing 737-800?
800
The half life of Au198 is 2 7 days When there are 800 atoms of Au198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8 1 days there are atoms of Au198 rema?
At 8.1 days, 400 atoms of Au198 would remain in the sample. This is because after 8.1 days, two half-lives of Au198 have passed, reducing the initial 800 atoms to 400.
