The answer is true.
Explanation:
The balance of trade is nothing but the country's exports minus the country's imports.
Exports means, what you produce in the country and sell it to other countries, whereas imports means what you get or buy from the other countries.
When you export more than you import, you have trade surplus .In that case the income from exports are more than the money spent. So you have a trade surplus.
When you import then you have a trade deficit or your income is low. Most of the countries want a trade surplus.
But when the Income from exports and the money spent on imports are the same , the situation is that of balance of trade equilibrium, where the income from exports is equal to the money its residents pay for the imports.
N=2 (always first number), l=1 (corresponds to p), ml=(-1 to 1)
Its like weight but not. mass is the amount of matter in a substance.
Answer:
C5H6N2O3
Explanation:
First the empirical formulas
C= 41.8÷12= 2.48
H= 4.7÷1= 4.7
O= 37.3÷ 16= 2.33
N= 16.3÷14 = 1.16
Divide by the smallest
C= 3.48/1.16=3
H= 4.7/1.16=4.1
O= 2.33/1.16=2
N= 1.16/1.16=1
Therefore empirical formula = C3H4NO2
To calculate molecular formula for osmotic pressure,
π= cRT
Or
π=cgRT/M where cg is in g/liter & T is temperature in Kelvin. Thus
π= (7.480*0.0821*300)/ M
M= 184.23/1.43
M= 128.83
To find molecular Formula
Molecular Mass= (empirical mass)n
128.83= (C3H4NO2)n
128.83= 86n
n= 1.5
Therefore the molecular formula
(C3H4NO2)1.5
= C4.5H6N1.5O3
Approximately
C5H6N2O3
