How is solution 1 made? What is its concentration? Need to know this to answer the question.

The percentage of nitrogen in the picric acid is 18,34 %.
The oxide N2O3 has a lower percent of mass nitrogen.
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
((16x40) +(18x60))/100 = 17.2
The molar mass of CaCN2 = 80.1021 g/mol
mass H2O =49.2g
LL
it can be calcium cyanamide or can be a mixture of C and CaCN2.
17.72%, please see the molecular weight calculator in related links
If 15 percent of a number N is 0.3 what is 45 percent of N

15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.
25 percent of n = 25% * n = 0.25 * n
40 percent of N = 0.4 x N
it can be calculated using the formula percentage composition of N =Gram molecular mass of nitrogen in the compound/ Gram molecular mass of compound *100
The mass percentage of N in HNO3 is 22,22 %.
