Answer:
Explanation:
1 mol of anything is 6.02 * 10^23 atoms (in this case)
x mol of 3.01 * 10^22
Set up the proportion
1/x = 6.02*10^23 / 3.01 * 10^22 Cross multiply
x*6.02 * 10^23 = 1 * 3.01 * 10^22 Divide by 6.02*10^23
x = 3.01 * 10^22 / 6.02*10^23
x = 1/(2 * 10)
x = 1/20 mol
x = 0.05 mol
Answer:
P₄O₆
Explanation:
The molecular formula is a whole number multiple of the empirical formula. that is, if the mole wt is 219.9 gms/mole and the empirical formula weight is 110 gms/mole*, then the whole number multiple is 219.9/110 = 2 => Molecular formula => (P₂O₄)₂ => P₄O₆.
