Answer is: mass of phosphorus is 37,16 grams.
m(C) = 36 g.
n(C) = m(C) ÷ M(C).
n(C) = 36 g ÷ 12 g/mol.
n(C) = 3 mol.
From balanced chemical reaction: n(C) : n(P) = 5 : 2.
n(P) = 2 · 3 mol ÷ 5.
n(P) = 1,2 mol.
m(P) = 1,2 mol · 30,97 g/mol.
m(P) = 37,16 g.
I believe the answer is A. 40 mL
The two effects do impurities have on the melting point of an organic compound are given as ,
- They tend to lower the overall melting point of the compound versus the value for he pure material .
- They ends to increase the range of the melting point values .
The impurities decreases the melting point of the substance of organic compounds . This is because there are unwanted particles which weaken the lattice structure of the solids crystal due to which it become less stable and melts before its original melting point.
Example : Let take a clay and add dirt hen it breaks easily from the points where there is dirt . This is essentially what happens with impurities

Trisulfur nonaiodide
Step-by-step explanation:
The name for a binary molecular compound has the form
Multiplying prefix+name of first element multiplying prefix+stem of second element element+ide (two words)
The multiplying prefixes for three and nine are tri and nona, respectively.
The stem of iodine is iod.
Put them together, and the name of S₃I₉ is
trisulfur nonaiodide.
