Question

How many atoms are in 0.075 mol of titanium?

Answer 1

The mass of titanium is = 47,867 g/1mol

Applying the rule of avrogado

1mol _______ 6,023 × 10^(23) at

0,075mol ___ x


X . 1mol = 0,075mol . 6,023 . 10^(23)at

X = 0,075 . 6,023 . 10^(23) at

X = 4,51 . 10^(22) atoms

Hope this helps

Answer 2

Answer: The number of atoms in given amount of titanium are $4.52\times 10^{22}$

Explanation:

We are given:

Moles of titanium = 0.075 moles

According to mole concept:

1 mole of an element contains $6.022\times 10^{23}$ number of atoms

So, 0.075 moles of titanium will contain = $(0.075\times 6.022\times 10^{23})=4.52\times 10^{22}$ number of atoms

Hence, the number of atoms in given amount of titanium are $4.52\times 10^{22}$
