Answer:
true
Explanation:
abiotic means nonliving and biotic means living
Answer:
yes I do think they mean the same thing
Explanation:
150 grams and 150 grams is the same thing and adding 0 to the end of a decimal does not change its value, you could even put 150.0000000 grams and it would still be equivalent to the other numbers
Answer: P= 1.64 atm
Explanation: solution attached.
Use Ideal gas law
PV= nRT
Derive for P
P= nRT/V R= 0.08205 L.atm/mol.K
Substitute the values.
Answer:
So 1 mole
Explanation:
PV = nRT
P = Pressure atm
V = Volume L
n = Moles
R = 0.08206 L·atm·mol−1·K−1.
T = Temperature K
standard temperature = 273K
standard pressure = 1 atm
22.4 liters of oxygen
Ok so we have
V = 22.4
P = 1 atm
PV = nRT
n = PV/RT
n = 22.4/(0.08206 x 273)
n = 22.4/22.40
n = 1 mole
Answer:
0.44 m is the molality
Explanation:
Molality means mol of solute in 1kg of solvent.
Solute → CdBr₂
Solvent → H₂O
Mass / Molar mass = 45.38 g / 272.21 g/m = 0.167 moles
1 g = 1x10⁻³ kg
375 g = 0.375 kg
0.167 m/0.375 kg = 0.44 m
