We can use the following formula when making diluted solutions from concentrated solutions
c1v1 = c2v2
where c1 is concentration and v1 is volume of the concentrated solution
and c2 is concentration and v2 is final volume of diluted solution
substituting the values in the equation
18.4 M x V = 0.1 M x 600 mL
V = 3.26 mL
volume of 3.26 mL of 18.4 M sulfuric acid solution should be taken and diluted upto 600 mL
Answer:
The correct answer is - 18.
Explanation:
The number of hydrogen atoms is indicated by the formula (NH4)2C7H10O2 that has two parts (NH4)2 and C7H10O2 then
Number of hydrogen atoms in (NH4)2 = 4*2= 8
number of H atoms in C7H10O2 = 10
then the total number of atoms = 10+8
= 18.
Thus, the correct answer is = 18 hydrogen atoms.
Answer: The atomic number is the number of protons in an atom of an element. In our example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus.
