Para convertir c a kelvin
K=c +273
Ósea que en vez de c vas a poner el número
Para de Kevin a Celsius
C=k - 273
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

Given mass of methane = 48.2 g
Molar mass of methane = 16 g/mol
Putting values in above equation, we get:

According to mole concept:
1 mole of compound contains
number of molecules.
So, 3.0125 moles of methane will contain =
number of molecules.
Hence, the correct answer is Option C.

A example it a because titration is weak Suck it greeeeeeeeennnnnn boyyyyyyyyyy
Im not sure if this will help but... your subscripts in a balanced equation are used to calculate the molar mass of the compound. And your coefficients are used to get the ratios. so for example we have this balanced equation
Be3N2 + 6H2O= 3Be(OH)2 + 2NH3 and you have to find the molar mass of 6h2o, you need to multiply the subscript by the atomic mass and then add them together to get the overall molar mass. * 2(1.01) + 16.00= 18.02 g/mol
and if a question wants to know the limiting or excess regent you would use the coefficients to find out the ratio between the compounds.
