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.)
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.
you can't have a part of a molecule - they have to be whole numbers
Question is not correct.MOLECULES SHOULD BE IN WHOLE NUMBERS.
2.45 X 10^23 molecules CH4 (1 mole CH4/6.022 X 10^23)
= 0.407 moles CH4
Just divide it by avagadro number.6.022x10^23.You can get the answer.0.40684mol
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
take (2.45x10^23)/(6.02x10^23) which gives you .407
Just divide it by avagadro constant.So the answer is 0.4068 × 10 23
moles = 245g / atomic weight of gallium = 245 / 69.72 = 3.51 moles
245 meters = 24,500 centimeters
There are 16 ounces in one pound. Therefore, 245 pounds is equal to 16 x 245 = 3920 ounces.
625 ml of nitrous acid contains 3,5625 moles (0,625*5,7) The total volume increases from 625 to 870 (625+245) 3,5625/0,87=4,09 M
245 cm = 8 feet 0.46 inches (approx).245 cm = 8 feet 0.46 inches (approx).245 cm = 8 feet 0.46 inches (approx).245 cm = 8 feet 0.46 inches (approx).
moles = 245g / atomic weight of gallium = 245 / 69.72 = 3.51 moles
1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
Potassium bromide is KBr, the atomic mass of this compound is ca. 119.1. no.moles = mass/relitive molecular mass, so in this case that's 245/119.1 = 2.057 moles of KBr.
Get moles NaCl and change 245 ml to 0.245 Liters. 3.8 grams NaCl (1 mole NaCl/58.54 grams) = 0.0650 moles NaCl Molarity = moles of solute/Liters of solution Molarity = 0.0650 moles NaCl/0.245 Liters = 0.27 M NaCl ----------------------
