Osmosis deals only with D. Water. Diffusion and Osmosis are relatively the same thing besides the fact that water is largely incorporated with the osmosis.
Explanation:
there are 21 atoms in Cu3N4
Answer:
0.375 M
Explanation:
NaOH(aq) + HBr(aq) ------------> NaBr(aq) + H2O(l)
Concetration of acid CA= 0.250M
Concentration of base CB= ????
Volume of acid VA= 30.0mL
Volume of base VB= 20.0mL
Number of moles of acid nA= 1
Number of moles of base nB= 1
CA VA/CB VB= nA/nB
CB= CAVAnB/VB nA
= 0.25× 30×1/20×1= 0.375 M
Answer:
The molar amount of the gas.
Explanation:
If the pressure, volume, and temperature of a gas are known than molar amount can be determine.
Formula:
PV = nRT
P = pressure
V = volume
R = general gas constant
T = temperature
n = number of moles
Example:
V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K
n = PV/RT
n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K
n = 2 / 22.413 /mol
n = 0.09 mol
I think the answer is hydrosphere
