Question

number of molecules in 44 mg of N20 ...pls answer

Answer 1

⚡here is your answer-

weight of N2O molecule = 44mg = 4.4g

no. of mole of N2O in 4.4 g

so, moles = mass/molecular weight
= 4.4/44
no. of molecule = mole× Avogadro's number

= 4.2/44×6.023×10²³ molecules ANS..

Answer 2

Answer:

6.22*10^20

Explanation:

Given Weight in grams = 0.044gm

Molecular weight of N2O = 44

Moles =0.044/44 =0.001

Number of molecules = 6.023?10^23

Such that

Molecules nu =6.023?10^23?0.001

= 6.023?10^20
