Answer:
The temperature is 419,1 K
Explanation:
We use the formula PV=nRT T=PV/nR
T=1,5 atm x 12,6 L/0,55 mol x 0,082 l atm/K mol
T= 419,0687361 K
Equation is as follow,
<span> 4 Na (s) + O</span>₂ <span>(g) → 2Na</span>₂<span>O (s)
According to equation,
91.92 g (4 moles) of Na produces = 123.92 g (2 moles) of Na</span>₂O
So,
17.4 g of Na will produce = X g of Na₂O
Solving for X,
X = (17.4 g × 123.92 g) ÷ 91.92 g
X = 23.45 g of Na₂O
