Explanation:
from definition of density we have
density=mass/volume
and density=55 mass=220g
volume=220/55
volume=4ml
or 4×10^-3l
Answer:
136.5886g of NH3
Explanation:
N2 + 3H2 = 2NH3
The mass of the N2 = 4.01
3H2 has a 2/1 ratio
This means the mass of 3H2 is twice as much as N2.
NH3= 2*N2 = 2*4.01 = 8.02 of NH3
Then, by multiplying the mass by MX (17.031)
8.02*17.031=136.5886g can be produced. Round it if needed.
Answer:
When you remember salt is soduim chloride so you put it on everything to feel smart.
Explanation:
Sorry im bad at this : - /
Answer:
The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride. The symbol for molality is a lower-case m written in italics.
In order to calculate the molality of a solution divide the moles of solute by the volume of the solution expressed in liters.
I did what I think you meant if it's wrong text me I'll fix it.
