How many molesin 168g hgs?

Answer 1

To find the number of moles in 168 grams of HgS (Mercury(II) sulfide), you first need to calculate the molar mass of HgS. The molar mass of mercury (Hg) is approximately 200.59 g/mol and sulfur (S) is about 32.07 g/mol, making the molar mass of HgS approximately 232.66 g/mol. Using the formula ( \text{moles} = \frac{\text{mass}}{\text{molar mass}} ), you can calculate:

[ \text{moles of HgS} = \frac{168 \text{ g}}{232.66 \text{ g/mol}} \approx 0.722 \text{ moles}. ]
