The mass of 2.88 × 10²² molecules of Bi (NO₃)₃ is 678.854 grams.
<h3>What is mass?</h3>
Mass is the quantity of matter in a physical body. Mass can be calculated by dividing the molar mass by the mass of the moles of the substance.
The molar mass of Bi (NO₃)₃ is 1461.99 g/mol
The molecules here is 2.88×10²²
The number of molecules will be divided by 6.023 x 10²³
2.88×10²² / 6.023 x 10²³ = 4.781 moles
Putting the value in the equation
mole = mass/molar mass
mass = moles x molar mass
4.781 x 1461.99 = 678.854 grams
Thus, the mass of 2.88×10²² molecules of Bi (NO₃)₃ is 678.854 grams
