Answer:
D Multiplying the number of moles of the sample by Avogadro's number
Explanation:
this question ask about the NUMBER OF ATOM in a sample
To calculate the number of atoms in a sample, find the molar mass of the substance, weigh the sample, divide the measured weight by the molar mass, then multiply by Avogadro's number.
so the answer is D.
The number of atoms in a sample can be determined by multiplying the number of moles of the sample by Avogadro's number.
According to the mole concept, the Avogadro number gives information about the number of atoms in 1 mole of a compound.
- By dividing the mass of the substance by its molar mass, the number of moles can be calculated.
- By multiplying the mass of the sample with the molar mass, moles per unit molar mass can be calculated.
- By dividing the number of moles of the sample by Avogadro's number, the information will be irrelevant.
- By multiplying the moles of the sample by Avogadro's number, the number of atoms in a sample can be determined.
