Answer:- A. 353.5 g
Solution:- The balanced equation is:
From this equation, there is 3:1 mol ratio between calcium chloride and calcium phosphate.
Grams of calcium chloride are converted to moles and these moles are multiplied by the mol ratio to get the moles of calcium phosphate. Finally the moles are multiplied by molar mass to get the grams of calcium phosphate.
Molar mass of 
= 40.078+2(35.45) = 110.978 g per mol
Molar mass of 
= 3(40.078)+2(30.974)+8(16.00)
= 120.234+61.948+128.00 = 310.182 g per mol
let's make the set up using dimensional analysis.
= 
Hence, 353.5 g of calcium phosphate will form and so the correct option is A.
Answer:
The solute that is most likely soluble in hexane is S₈
Explanation:
S₈ is a non-polar solute that exhibits the same characteristics and properties as hexane. Following the common principle "like dissolves like"; polar compounds will be soluble in polar solvents while non-polar compounds will be soluble in non-polar solvents. As such, since S₈ is non-polar, then it will be soluble in hexane.
In one glucose you have
6 carbon atoms
12 hydrogen atoms
6 oxygen atoms
if you have 3 then you are going to multiply the atoms by 3. 6 times 3 is 18.
you have 18 OXYGEN MOLECULES
The answer to the question is D
