Exercise 950 grams ofArgon (Ar) gas is utilized daily for the production of a specific pharmaceutical product.What is the number of moles of argon present in this 950 g sample?

To find the number of moles of argon in a 950 g sample, we need to use the molar mass of argon. The molar mass of argon (Ar) is approximately 39.948 g/mol.<br /><br />The formula to calculate the number of moles is:<br /><br />\[ \text{Number of moles} = \frac{\text{Mass of the substance}}{\text{Molar mass of the substance}} \]<br /><br />Given:<br />- Mass of argon = 950 g<br />- Molar mass of argon = 39.948 g/mol<br /><br />Plugging in the values:<br /><br />\[ \text{Number of moles} = \frac{950 \, \text{g}}{39.948 \, \text{g/mol}} \]<br /><br />\[ \text{Number of moles} \approx 23.75 \, \text{moles} \]<br /><br />Therefore, there are approximately 23.75 moles of argon in the 950 g sample.
