Calculate the mass of one nitrogen molecule N2.
| May 9, 2021 | education
Given M = 28 * 10 ^ -3 kg / mol, where M is the molar mass of nitrogen, numerically equal to 6 * 10 ^ 23 It is necessary to find the mass of one nitrogen molecule N2, it is denoted as mo.
The mass of one molecule is calculated using the following formula:
mo = M: Na;
where Na is Avogadro’s constant, numerically equal to 28 * 10 ^ -3 denoting the number of particles per unit amount of matter.
mo = M: Na = 28 * 10 ^ -3: 6 * 10 ^ 23 = 4.67 * 10 ^ -26 kg.
Answer: the molar mass of one nitrogen molecule is mo = 4.67 * 10 ^ -26 kg.
