To convert micromoles (μmol) of a substance to grams, you need to know the molecular weight of the substance. In this case, you want to convert micromoles of CS2 (carbon disulfide) to grams.
The molecular weight of CS2 is approximately 76.14 grams per mole.
To convert micromoles to grams, you can use the following formula:
Mass (grams) = Number of micromoles (μmol) × Molecular weight (g/mol)
Mass = 110.9 μmol × 76.14 g/mol ≈ 8,448.126 grams
So, 110.9 micromoles of CS2 is approximately equal to 8,448.126 grams.
