Answer: The purpose of a hypothesis is to find the answer to a question.
Explanation:
A hypothesis is a statement which is written as a source of prediction which is based upon the assumption of the cause of a natural event or process. The purpose of the hypothesis is basically to find the relevant answers to the scientific question. It is based upon few evidences and the entire statement of the hypothesis is tested using experimental procedures.
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:
Number of moles = 1.57 mol
Explanation:
Given data:
Mass of propanol = 94.1 g
Molar mass of propanol = 60.1 g/mol
Number of moles of propanol = ?
Solution:
Formula:
Number of moles = mass/molar mass
by putting values,
Number of moles = 94.1 g/ 60.1 g/mol
Number of moles = 1.57 mol
