Question

Find the molar mass of a compound if there are 0.163 moles in a 38.7 gram sample.

Enter your answer to three significant figures in the space provided, being sure to include units

Answer 1

The molar mass of the compound is found by dividing the mass (38.7 grams) by the number of moles (0.163 moles), which results in approximately 237.4 g/mol.

Step-by-step explanation:

To find the molar mass of a compound, you need to divide the mass of the compound by the number of moles present. In this case, if we have 0.163 moles of a substance that weighs 38.7 grams, the molar mass (M) is calculated as:
M = mass (g) / moles (mol)
M = 38.7 g / 0.163 mol

Calculating the above gives us the molar mass of the compound, which is approximately 237.4 g/mol.
Remember, molar mass is a conversion factor that is always used in chemistry to convert between the mass of a substance and the number of moles. Knowing the molar mass is essential when working in a lab to measure the correct amounts of a substance.
