Question

Calculate number of particle in 46 gram of an atom

Answer 1

Hi!

I guess that your question is wrong! Instead of an there should be Na

Answer:

atomic mass of Na=23u

Number of particles=Number of Moles x N

⇒(given weight/ Gram atomic weight) x 6.023 x 10²³

=(46/23)x 6.023 x 10²³

=2x 6.023 x 10²³

⇒12.046 x 10 ²³Na particles

∴46 g of Na contains 12.044 x 10 ²³

Hope you are helped!

Answer 2

atomic mass of Na=23u

• No.of particles=No.of molesxN
• =[giveb weight/gram atomic weight]x6.023x10∧23
• [46/23]x6.023x10∧23
• 2x6.023x10∧23
• =12.046x10∧23 Na particles
• 4.6g of Na contains 12.044x10∧23
