1.34 grams of MgNH4PO4*6H2O
Molar mass= 245.1 grams per mole
Moles of MgNH4PO4*6H2O=
(1.34 grams)(1 mole/245.1 grams fertilizer)=0.0054671563 moles fertilizer
MgNH4PO4*6H2O has 1 mole of Phosphorous, so:
0.0054671563 moles fertilizer(1 mole Phosphorous/1 mole fertilizer)
0.0054671563 moles Phosphorous (30.97 grams/ 1 mole)
=0.1693178295 grams Phosphorous
Answer : The partial pressure of nitrogen gas in the mixture is, 9.88 atm
Explanation :
According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.
Formula used :
where,
= total pressure of gas = 13.6 atm
= partial pressure of helium gas = 1831 torr = 2.41 atm
= partial pressure of argon gas = 997 torr = 1.31 atm
Conversion used: (1 atm = 760 torr)
= partial pressure of nitrogen gas = ?
Now put all the given values in the above formula, we get:
Thus, the partial pressure of nitrogen gas in the mixture is, 9.88 atm
Influencing Behavior is the only incorrect option. Everything else is correct including drawing conclusions.
Answer:
If you're talking about a Sulfur ion, there are 13 electrons.
Explanation:
Sulfur originally had 16 electrons in its atom.
A charge of +3 means that sulfur must have lost 3 electrons, and therefore needs to gain back 3 electrons to achieve its atomic configuration.
Answer:
The concentration is 0.025 M.
Explanation:
We will use beer law to find the concentration.
A = εmCl
This law relate to the linear equation Y = mx + b in following way,
A = y = absorbance
m = εm = slope or extinction coefficient in beer law.
x = c = concentration
and l is length which is 1 cm
Thus equation can be written as,
A = εmc + b
A - b / εm = c
in order to find the concentration we will abstract the intercept from absorbance and then divide it by the slop.
0.02 - 0.011 / 0.36 = c
c =0.009
c = 0.025 M.
