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:
1.332 Molar is the molarity of the glucose solution.
Explanation:
Molarity of the solution is the moles of compound in 1 Liter solutions.
Mass of glucose = 60.00 g
Molar mass of glucose = 180.2 g/mol
Volume of the solution = V = 250.0 mL = 0.250 L
(1 mL = 0.001 L)
1.332 Molar is the molarity of the glucose solution.
The balanced reaction
is:
AgNO3 + NaCl = NaNO3 + AgCl
<span>We are given the amount of silver nitrate to react with sodium chloride. This
will be our starting point.</span>
15.0 mol AgNO3 (1 mol AgCl / 1
mol AgNO3 ) =15.0 mol AgCl
The amount of moles produced is the same with the amount of the given reactant since they only one is to one ratio.
B, more kinetic energy means more collisions and thus more reactions according to collision theory.
The evidence that a chemical reaction occurred is can be change in color , formation of a precipitate , Here in the case when 6 m HCl to the solution of sodium acetylsalicylate, the formation of precipitate that is of aspirin takes places that can be taken as a evidence that a reaction is occured. The reaction can be seen in the image attached.
