Answer:
6.022 x 10²³
Explanation:
Data Given:
mass of carbon = 12.01 g
individual particles = 6.02 x 10²³
number of atoms = ?
Solution:
Formula used to find the number of atoms
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
So, first we have to find number of moles
Formula to find no. of moles
no. of moles = mass in grams/ molar mass. . . . . (2)
molar mass of Carbon = 12.01 g/mol
Put values in eq.2
no. of moles = 12.01 g / 12.01 g/mol
no. of moles = 1 mol
Now put the values in eq. 1
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
1 mol = number of atoms / 6.022 x 10²³
Rearrange the above equation
number of atoms = 1 mol x 6.022 x 10²³
number of atoms = 6.022 x 10²³
So it is 6.022 x 10²³ atoms in 12.01 grams of carbon. This 6.022 x 10²³ also Known as Avogadro's number that is one mole of any substance consists this number of atoms.
Answer:
118201.68m6^2
Explanation: scientific notation
Since we started with 50 mL of the titrant and 32 mL of a 2.5 M standard solution. Using the dilution equation M2 = 2.5 M × 32 mL/50 mL
Titration is a means of determining the concentration of a solution by using another solution of known concentration. The solution of known concentration is called the standard solution.
The titrant is the solution in the flask. We started with 50 mL of this solution, then we added 32 mL of the standard solution. Using the dilution formula;
M2 = 2.5 M × 32 mL/50 mL
