<u>Answer:</u> The molecular formula of compound is C_6H_6O_6

<u>Explanation:</u>

We are given:

Empirical formula of compound = CHO

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

n=\frac{\text{Molecular mass}}{\text{Empirical mass}}

We are given:

Mass of molecular formula = 180 g/mol

Mass of empirical formula = 29 g/mol

Putting values in above equation, we get:

n=\frac{180g/mol}{29g/mol}=6.20\approx 6

Multiplying this valency by the subscript of every element of empirical formula, we get:

C_{(1\times 6)}H_{(1\times 6)}O_{(1\times 6)}=C_6H_6O_6

Hence, the molecular formula of compound is C_6H_6O_6

You have 35 ml of water and u drop a rock in so now it is 40ml of water what is the volume of the rock
Soloha48 [4]
Okay
40ml-35ml=5ml
5ml is the volume of the rock
1ml=1cm3
hence the volume of the rock is 5cm3
