Convert 7.10 grams of sodium to atoms.

The answer is option A.

To convert 7.10 grams of sodium to atoms we first find the number of moles and use the formula

N = n × L

N = number of entities

n = number of moles

L = Avogadro's constant which is

6.02 × 10^23

number of moles (n) = mass / Molar mass (M)

Molar mass of sodium = 23g/mol

mass = 7.10g

n = 7.10/23 = 0.309 moles

So number of sodium atoms (N) is

N = 0.309 × 6.02 × 10^23

N = 1.86*10^23 atoms

Hope this helps you.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
