Answer: (A) 44.0 g/mol

Explanation:

Molar mass of a compound is the sum total of all the individual masses of the constituent elements present in the compound.

Molar mass of C3H8 =

C = 12.0 g/mol

H = 1.00 g/mol

Molar mass of C3H8 = (12*3) + (1*8) = 36 + 8 = 44 g/mol.

Molar mass of C3H8 = 44g/mol

C = 12 g/mol

H= 1 g/mol

C3H8

C: 12 g/mol * 3 = 36 g/mol

H: 1 g/mol * 8 = 8 g/mol

36 + 8 = 44 g/mol

Answer: A) 44.0 g

If 3.00 g of titanium metal is reacted with 6.00 g of chlorine gas, Cl2, to form 7.7 g of titanium (IV) chloride in a combinatio

Crank

Ti + 2 Cl2 → TiCl4

(3.00 g Ti) / (47.867 g Ti/mol) = 0.062674 mol Ti

(6.00 g Cl2) / (70.9064 g Cl2/mol) = 0.084619 mol Cl2

0.084619 mole of Cl2 would react completely with 0.084619 x (1/2) = 0.0423095 mole of Ti, but there is more Ti present than that, so Ti is in excess and Cl2 is the limiting reactant.

(0.084619 mol Cl2) x (1 mol TiCl4 / 2 mol Cl2) x (189.679 g TiCl4/mol) = 8.025 g TiCl4 in theory

(7.7 g) / (8.025 g) = 0.96 = 96% yield TiCl4

Mendeleev positioned elements in the periodic table in increasing order of their atomic numbers, such that elements having identical chemical properties and characteristics plunge into the same group.

What is Mendeleev's periodic table called?

In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.

Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
He also imagined having other elements with possessions similar to those of these other elements.
In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.
