<u>Answer:</u> The mass of phosphorus that is present for given amount of calcium is 28.53 g.
<u>Explanation:</u>
We are given:
Mass of calcium = 50 grams
The chemical formula of calcium phosphate is
Molar mass of calcium = 40 g/mol
Molar mass of phosphorus = 31 g/mol
In 1 mole of calcium phosphate, 120 grams of calcium is combining with 62 grams of phosphorus.
So, 50 grams of calcium will combine with = of phosphorus.
Hence, the mass of phosphorus that is present for given amount of calcium is 28.53 g.
I think the answer is number (4)
The answer is metal. Metals are always named first in ionic compounds, like KNO3 for example. I hope this helps!
The answer would be periods 6-7 :)
