[?] g Ar


Sagot :

To determine the mass of argon in grams when given the number of moles and the molar mass, follow these steps:

1. Identify the molar mass of argon:
The molar mass of argon ([tex]\(Ar\)[/tex]) is [tex]\(39.95 \, \text{g/mol}\)[/tex].

2. Identify the number of moles of argon:
The number of moles given is [tex]\(3.41\)[/tex] moles.

3. Use the formula to calculate the mass:
The mass of a substance (in grams) is obtained by multiplying the number of moles by the molar mass:
[tex]\[ \text{mass} = \text{molar mass} \times \text{number of moles} \][/tex]

4. Substitute the known values into the formula:
[tex]\[ \text{mass} = 39.95 \, \text{g/mol} \times 3.41 \, \text{moles} \][/tex]

5. Calculate the result:
[tex]\[ \text{mass} \approx 136.2295 \, \text{g} \][/tex]

Therefore, the mass of [tex]\(3.41\)[/tex] moles of argon is approximately [tex]\(136.2295\)[/tex] grams.
