Question

The ratio of mass of a Titanium atom to the mass of a Carbon atom is 4: 1. Then, the molar mass of Titanium is :
(A) 3 g
(B) 48 g
(C) 12 g
(D) 24 g

Answer should be (A).​

Answer 1

Hi there,

I think it can't be a=3 g

Fro the molar ratio Ti:C = 4:1

Molar mass of titanium is 4 time molar mass of carbon

So, the molar mass of Ti is 48 gms

Hope its useful

Answer 2

Answer : The correct option is, (B) 48 g

Explanation :

The relation between mass and the molar mass is:

$\frac{\text{Mass of titanium}}{\text{Mass of carbon}}=\frac{\text{Molar mass of titanium}}{\text{Molar mass of carbon}}$

As we are given that the ratio of mass of a Titanium atom to the mass of a Carbon atom is 4 : 1 and we know that the molar mass of carbon is 12 g/mole.

Now put all the values in the above relation, we get the molar mass of titanium.

$\frac{4}{1}=\frac{\text{Molar mass of titanium}}{12g/mole}$

$\text{Molar mass of titanium}=48g$

Therefore, the molar mass of titanium is, 48 g
