Question

the empirical formula of the compound is ch2o. it's vapour density is 90. calculate molecular formula of the compound.​

Answer 1

Answer:

For calculation of molecular mass in this question: Given, empirical formula of compound = CH2O. And vapour density of compound = 90. Therefore, the molecular formula of the compound is C6H12O6.

Explanation:

Hope that might help you dear

Answer 2

Answer:

Explanation:

we know that 2 times the vapourdensity = molecular mass of the compound

thus mol. mass =2 (90)

                         = 180

then find the mol. mass of empirical formula= 30

thus the number with which we have to multiply the empirical formula is the molecular mass of required compound/molecular mass of empirical formula

= 6

thus multiply empirical formula 6 times we get

c6 h12o6
