Question

Calculate the mass of urea containing one gram atom h

Answer 1

The formula of urea is:


CH4N2O


Molar mass of urea = 12+4+28+ 16 = 60g/mol


1 mole of urea contain 4 moles of hydrogen atoms of mass = 4g



4g H are contained in 60g urea

∴∴ 1g H are contained in = (1x60)/4


                                        = 15g




15g of urea contain 1g of H

Answer 2

Answer:

Explanation:

The formula of urea is:

CH4N2O

Molar mass of urea = 12+4+28+ 16 = 60g/mol

1 mole of urea contain 4 moles of hydrogen atoms of mass = 4g

4g H are contained in 60g urea

∴∴ 1g H are contained in = (1x60)/4

= 15g

15g of urea contain 1g of H
