You start by diving each quantity given by the atomic wight of each element:
Phosphorus (P) 
Hydrogen (H) 
Then you divide by the lowest number:
for phosphorus
for hydrogen
So the empirical formula will be:

Answer:
i dont know i do this for points
Explanation:
Answer:
The answer to your question is 1.11 M
Explanation:
Data
volume 1 = 287 ml
concentration 1 = 1.6 M
volume 2= 412 ml
concentration 2 = ?
Formula
Volume 1 x concentration 1 = Volume 2 x concentration 2
Solve for concentration 2
concentration 2 = (volume 1 x concentration 1) / volume 2
Substitution
concentration 2 = (287 x 1.6) / 412
Simplification
concentration 2 = 459.2 / 412
Result
concentration 2 = 1.11 M
Titanium is ductile and has high resistance for heat despite its strength.
Titanium (Ti), is a Group 4b chemical transition element, it has a silvery gray appearance. Its characteristics are as follows
- known as the strongest metal with high rigidity
- low-corrosion resistance
- low density
- heat resistance.
Because of these features, Titanium is widely used in building aircraft, missiles, and ships and also in the production of prosthetics.
