How many molecules are in 0.3672 moles of LiBr?

2.21×10²³molecules

Explanation:

Hello,

The question requires us to calculate the number of molecules present in a given number of mole.

Numbe of mole = 0.3672 moles

According to mole ratio concept, one mole of any substance is equal to Avogadro's number of particles, atoms or molecules. I.e,

1 mole = Avogadro's number

Avogadro's number = 6.022×10²³ atoms/molecules/particles or ions

1 mole = 6.022×10²³molecules

0.3672 mole = x molecules

x = 0.3672 × 6.022×10²³

X = 2.21×10²³molecules

Therefore, 0.3672moles of LiBr contains 2.21×10²³molecules

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
