Avagadros constant states that 1 mol of any substance is made of 6.022 x 10^23 units.
These units could be atoms making up elements or molecules making up compounds.
1 mol of molecular oxygen (O2) is made of 6.022 x 10^23 molecules of O2
The mass of 1 mol of O2 is 32 g/mol
This means that the number of oxygen molecules in 32 g are 6.022 x 10^23 molecules
Therefore in 7.36 g of oxygen gas there are - 6.022 x 10^23 /32 g/mol x 7.36 g = 1.39 x 10^23 oxygen molecules
Answer is 1.39 x 10^23 oxygen molecules
Hi.
You can calculate mass percent by dividing the mass by the total mass of the compound & multiplying by 100.
28.8 ÷ (171.2 + 28.8) = 0.144
0.144 · 100 = 14.4
I believe the mass percent of the hydrogen in the compound is 14.4%

Answer:
N with a charge of (-3) is nitride
Explanation:
Well in everything we have protons and electrons, eg. In static electrisity in a balloon when you rub the balloon on a material like your hair all the protons come off and into your hair which makes your hair go upright and funny and the ballon is desperate to get back the protons so it sticks to surfaces to gain there protons to ballance out the electrons it allready has for it to be nuteral again. Because its important for everything that can be to be nuteral
