128.3 grams of methane (ch4) is equal to how many moles of methane

Answer : The moles of methane are, 8.01875 moles

Explanation : Given,

Mass of = 128.3 g

Molar mass of = 16 g/mole

Now we have to calculate the moles of methane.

Formula used :

Now put all the given values in this formula, we get the moles of methane.

Therefore, the moles of methane are, 8.01875 moles

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
