Answer:

Explanation:

1 ST METHOD

GIVEN DATA:

number of molecules=6.022×10²²molecules

Avogodro's number Na=6.022×10²²

TO FIND:

number of moles

SOLUTION:

As we knom that number of moles=number of molecules/Na

number of moles=6.022×10²²/6.022×10²²

number of moles=1 moles

2ND METHOD:

AS WE KNOW THAT A MOLE OF A SUBSTANCE CONTAINS 6.022×10²² PARTICLES OF THAT SUBATANCE SO

1MOLE OF CO2=6.022×10²²MOLECULES OF CO2

If the half-life of a radioactive substances is 590 million years and you have 40 atoms of it, how many half-lives will have pas
Nady [450]

Answer:

3

Explanation:

Applying,

2^{n'} = R/R'............... Equation 1

Where n' = number of halflives that have passed, R = Original atom of the substance, R' = atom of the substance left after decay.

From the question,

Given: R = 40 atoms, R' = 5 atoms

Substitute these values into equation 1

2^{n'} = 40/5

2^{n'} = 8

2^{n'} = 2³

Equation the base,

n' = 3
