1ft=.3048meter
So if we have 2063ft and want it in meters we just do a simple unit conversion.
(2063ft)(.3048meters/1ft)=628.8meters. Here ft cancel out and leave us with meter units.
Any questions please feel free to ask. Thank you.
Molarity = 1.5
molarity = moles/liters
m= 3/2
m= 1.5
Answer:
1.) The balanced equation is 3MgO(s) + 2Fe(s) ===> Fe2O3(s) + 3Mg(s)
2.) 20g of Fe2O3 will be produced by 20 ×120/160 = 15g of MgO
Explanation:
THE CORRECT EQUATION IS: MgO(s) + ___ Fe(s) ===> Fe2O3(s) + ___ Mg(s)
The balanced equation is: 3MgO(s) + 2Fe(s) ===> Fe2O3(s) + 3Mg(s)
molar mass of 3MgO = 3(24 + 16) = 120
Molar mass of Fe2O3 = 2 X 56 + 3 X 16
=112 +48 =160
From the equation, 120g of MgO Produced 160g of Fe2O3
Therefore 20g of Fe2O3 will be produced by 20 ×120/160 = 15g of MgO.
Answer:
91.5 mol
Explanation:
Volume of gas = 70 L
Temperature = 25°C
Pressure = 32 atm
Moles of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
25+273.15 = 298.15 K
By putting values,
32 atm × 70 L = n ×0.0821 atm.L /mol.K × 298.15 K
2240 atm.L = n ×24.48 atm.L /mol
n = 2240 atm.L / 24.48 atm.L /mol
n = 91.5 mol
