The molar mass of PH3 is 34 g/mol, therefore the moles
is:
moles PH3 = 225 g / (34 g/mol)
moles PH3 = 6.62 mol
The balanced equation is:
4PH3(g) + 8O2(g) → P4O10(g) + 6H2O
We see that 4 mol of PH3 is required for every mol of
P4O10, therefore the number of moles of P4O10 is:
moles P4O10 = 6.62 mol * (1/4)
moles P4O10 = 1.65 mol
The molar mass of P4O10 is 283.89 g/mol, so the mass is:
mass P4O10 = 1.65 mol * 283.89 g/mol
mass P4O10 = 469.67 grams ~ 470 grams
1694520 joules

Answer:
0.861842
Explanation:
One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Example #1: Convert 0.875 atm to mmHg. Solution: multiply the atm value by 760.0 mmHg / atm.
No, although to the sound it seems correct but is incorrect
