Answer:
The answer to your question is 27 g of Al
Explanation:
Data
mass of Al = ?
moles of Al₂O₃ = 0.5
The correct formula for the product is Al₂O₃
Balanced chemical reaction
4Al + 3O₂ ⇒ 2Al₂O₃
Process
1.- Calculate the molar mass of the product
Al₂O₃ = (27 x 2) + (16 x 3)
= 54 + 48
= 102 g
2.- Convert the moles of Al₂O₃ to grams
102 g ---------------- 1 mol
x ---------------- 0.5 moles
x = (0.5 x 102) / 1
x = 51 g of Al₂O₃
3.- Use proportions to calculate the mass of Al
4(27) g of Al --------------- 2(102) g of Al₂O₃
x --------------- 51 g
x = (51 x 4(27)) / 2(102)
x = 5508 / 204
x = 27 g of Al

Explanation:
Answer:
Volume of the 
gas at 44°C is <u>258 ml.</u>
Explanation
here,
using Charles' law ,
where , V= initial volume v= final volume
T=initial temperature t = final temperature
Given - pressure is constant ,
so , putting the values -
V= 240ml
T= 22 + 273K = 295K (since converting celsius into kelvin that
is +273K )
v =?
t = 44+ 273K = 317K
Now , putting the given values in charles' law ,
240ml x317K = v x 295K (through cross multiplication )
v =
= 258ml .
thus ,<u> the volume of carbon dioxide in a container at 44°C IS 258ml .</u>
