The answer is 1,560 hope this helps if u multiply all of it
The gram formula mass of P2O5 is 31*2 + 16*5 =142. The mole number of P2O5 is 0.380/142=0.00268 mol. There is 7 atom in one P2O5 molecule. And there is 6.02 * 10^23 molecule per mol. So the answer is 1.13*10^22 atoms.
<span>Saturated hydrocarbons are organic compounds that contain only single bonds between the carbon atoms. They are known to be the simplest organic compounds. They are termed as such because they are saturated with water. Examples are the alkanes (ethane, methane, propane, butane, etc.).</span>
Answer:
C. Refining
Explanation:
Refining process removes elements from a substance
Answer:
1. 0.35 moles NaOH
2.
moles 
3. 505.4 g Pb
4. 1.46 g HCl (if that is wrong it's 1.5 g HCl due to sig figs)
5.
atoms of Ag
6.
atoms of Cu
Explanation:
1. The mass of NaOH is 40g. 22.99(Na)+16(O)+1.01(H)=40 g
14 g NaOH *
= 0.35 moles of NaOH
2. Mass of
0.05 g
×
3. mass of Pb = 106.4 g
4.75 moles Pb×
4. mass of HCl = 1.01 +35.45 = 36.36 g
0.04 mol HCl x 
5. 5.00 mol Ag x
6.
Cu x
atoms of Cu
