First write a balanced equation...
P4 + 5 O2 ⇒ 2P2O5
mole of P4 = 136 ÷ (4×31) = 1.09677
MOLE RATION OF P4 : P2O5 IS 1:2
THAT IS 1 mole of p4 reacts to give 2 moleof p2o5
∴ 1.09677 mole............................. (2×1.09677) =2.19....mole
maximum number of mole = 2.19 mol
Answer:
The answer is
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual mass = 6.25 g
error = 6.25 - 6 = 0.25
So we have
We have the final answer as
<h3>4 %</h3>
