How many moles are present in 2.45 molecules of CH4?

Answer 1

To find moles, simply divide the number of representative particles (in this case, molecules of methane) by Avogadro's number (6.02x1023.)

2.45x1023/6.02x1023 = approx. 0.41 moles (the exponents cancel out.)

Answer 2

To find the number of moles from molecules, divide the given number of molecules by Avogadro's number (6.022 x 10^23 molecules/mol). 2.45 molecules of CH4 divided by Avogadro's number equals 4.07 x 10^-24 moles of CH4.

Answer 3

It can be calculated for calculation's sake, but it should be known that it is impossible to have 2.45 molecules of something. How do you have 9/20 of a molecule of CH4? You can only have a whole number of molecules - 5 molecules of H2 or 5.16 × 1024 molecules of NH3, but not 9.651 molecules of N2O.

To convert molecules to moles, divide the number of molecules by Avogadro's constant, 6.02 × 1023. Therefore, if you somehow got your hands on 2.45 molecules of CH4, you would have 4.07 × 10-24 moles.

Answer 4

you can't have a part of a molecule - they have to be whole numbers

Answer 5

Question is not correct.MOLECULES SHOULD BE IN WHOLE NUMBERS.

Answer 6

2.45 X 10^23 molecules CH4 (1 mole CH4/6.022 X 10^23)

= 0.407 moles CH4

Answer 7

Just divide it by avagadro number.6.022x10^23.You can get the answer.0.40684mol

Answer 8

well u take your given (2.45 x 1023), and divide it by Avogrados number (6.02 x 1023) and you get your answer. 0.406 moles

Answer 9

take (2.45x10^23)/(6.02x10^23) which gives you .407

Answer 10

Just divide it by avagadro constant.So the answer is 0.4068 × 10 23
