Answer: There are
atoms of hydrogen are present in 40g of urea,
.
Explanation:
Given: Mass of urea = 40 g
Number of moles is the mass of substance divided by its molar mass.
First, moles of urea (molar mass = 60 g/mol) are calculated as follows.

According to the mole concept, 1 mole of every substance contains
atoms.
So, the number of atoms present in 0.67 moles are as follows.

In a molecule of urea there are 4 hydrogen atoms. Hence, number of hydrogen atoms present in 40 g of urea is as follows.

Thus, we can conclude that there are
atoms of hydrogen are present in 40g of urea,
.
Answer:
0.013 M/s
Explanation:
Given data
- Initial concentration of BrO⁻: 0.56 M
- Final concentration of BrO⁻: 0.14 M
Since the final concentration of BrO⁻ is lower than the initial concentration of BrO⁻, BrO⁻ is dissapearing. The rate of dissapearance of BrO⁻ is:
rBrO⁻ = - Δ [BrO⁻] / t
rBrO⁻ = - (0.14 M - 0.56 M)/ 33 s
rBrO⁻ = 0.013 M/s
