The question is incomplete, the complete question is :
Calculate the approximate number of atoms in a bacterium. Assume the average mass of an atom in the bacterium is 10 times the mass of a hydrogen atom.(Hint the mass of hydrogen atom is on order of 
kg and the mass of bacterium is on order of 
kg
Answer:
The total numbers of atom in bacterium are 
.
Explanation:
Mass of hydrogen atom, m= 
kg
Mass of bacterium , M= kg
Mass of bacterium atom =m'
Given ; 
let the number of atoms in bacterium be N
The total numbers of atom in bacterium are .
Answer:
Explanation:
Given parameters:
Concentration of H₃O⁺ = 5.6 x 10⁻²M
Solution:
To solve for the concentration of H₃O⁺ in the solution, we simply use the expression below:
pH = -log₁₀[H₃O⁺]
where [H₃O⁺] = 5.6 x 10⁻²M is the concentration of H₃O⁺
pH = -log₁₀[5.6 x 10⁻²] = - x -1.25 = 1.25
Use the formula pv=nRt and you will get the answer
