Answer:
what subject is this and how can u draw the structure :)
The mass of ONE mole is the same thing as the atomic mass, so the mass of one mole of Al is 26.99
The volume of air mattress is = 1.127 L
<u><em>calculation</em></u>
The volume of air is calculated using the ideal gas equation
that is Pv=nRT where,
P(pressure)= 3.5 kilopascals convert into Atm
1 atm =0.00987 KPa
?atm = 3.5 Kpa
= (3.5 kpa x 1 atm) / 0.00987 kpa =354.6 atm
V(volume) = ?
n( no of moles) = 16.5 moles
R (gas constant)= 0.0821 L.atm/mol.K
T(Temperature) = 295 K
make V the subject of the formula V=nRT/P
V= ( 16.5 moles x 0.0821 atm/mol.K x 295 k) /354.6 atm =<u><em>1.127 L</em></u>
