Question

The mass of 0.473 mol of titanium metal sample isa) 47.87 gb) 22.6 gc) 1 25 x 1023 gd) 2.88 x 1023 g

Answer 1

The mass of titanium is 22.6 grams

OPTION B

Explanation

Given data:

The mole of titanium = 0.473 mole

Let x be the mass of titanium in grams

The mass of titanium can be calculated using the below formula

`\text{mole = }\frac{\text{ reacting mass}}{\text{ molar mass}}`

From the above formula, you can see that the molar mass of titanium is not given, and that can easily be determined using our periodic table.

From the periodic table, the molar mass of titanium is 47.867 g/mol.

The next thing is t substitute the value into the above formula

`\begin{gathered} 0.473\text{ = }\frac{\text{ x}}{\text{ 47.867}} \\ \text{cross multiply} \\ x\text{ = 0.473 }\cdot\text{ 47.867} \\ x\text{ = 22.64 grams} \end{gathered}`

since x represents the mass of titanium in grams, therefore, the mass of titanium is 22.6 grams
