QuestionCalculate the number of moles of CS2 with a weight of 4.20 g and molar mass 76.13 g/mol using the formula:
Number of moles = 4.20g76.13g/mol\frac{4.20 \, \text{g}}{76.13 \, \text{g/mol}}.

STEP 1

Assumptions1. The molar mass of C (Carbon) is12.01 g/mol. The molar mass of (ulphur) is32.06 g/mol3. The molar mass of CS is calculated as Molar mass of C +(Molar mass of) =12.01 g/mol +(32.06 g/mol) =76.13 g/mol4. The weight of CS is4.20 grams5. The number of moles is calculated using the formula Number of moles = \frac{weight of the substance (g)}{molar mass of the substance (g/mol)}

STEP 2

We need to calculate the number of moles of CS2. We can do this using the given formulaNumberofmoles=weightofthesubstance(g)molarmassofthesubstance(g/mol)Number\, of\, moles = \frac{weight\, of\, the\, substance\, (g)}{molar\, mass\, of\, the\, substance\, (g/mol)}

STEP 3

Now, plug in the given values for the weight of the substance (CS2) and molar mass of the substance (CS2) to calculate the number of moles.
Numberofmoles=.20g76.13g/molNumber\, of\, moles = \frac{.20\, g}{76.13\, g/mol}

STEP 4

Calculate the number of moles.
Numberofmoles=4.20g76.13g/mol=0.055molesNumber\, of\, moles = \frac{4.20\, g}{76.13\, g/mol} =0.055\, molesThe number of moles of CS2 is0.055.
