Question

calculate the mass of 6.022×10236.022×1023 molecule of NH4cl​

Answer 1

Answer:

53.5gram

Explanation:

number of moles = number of molecule ÷ avogadro's number

=> moles = 6.022 × 10²³ ÷ 6.022 × 10²³ = 1 mole

mass of 1 mole of NH4Cl = 1 × molar mass

=> mass of 1 mole of NH4Cl = 53.5g

Answer 2

Mass of 6.023×10²³ molecule of NH₄Cl is calculated as  53.5 gm

Molar mass is defined as the mass of a sample of that chemical compound divided by the amount of the sample.

Explanation:

Number of molecules =n×Na

Where Na is 6.023×10²³

Molecule of NH₄Cl = ​6.022×10²³

⇒6.022×10²³=n × 6.023×10²³

⇒n=1

Thus moles =Mass ÷Molecular mass

moles =1,

Molecular mass=53.5

1 =Mass ÷53.5

Mass =53.5 gm

Mass of 6.023×10²³ molecule of NH₄Cl is calculated as  53.5 gm
