Question

I weigh out 2.00 g of a compound with a molar mass of 42.00 g/mol. How many moles of the compound is this?

Answer 1

The molar mass of a compound is computed by adding up the atomic masses of all the elements in the compound. To find out how many moles of the compound is represented by 2.00 g, use the formula moles = mass / molar mass.

Step-by-step explanation:

The molar mass of a compound is computed by adding up the atomic masses of all the elements in the compound. In this case, the molar mass of the compound is 42.00 g/mol. To find out how many moles of the compound is represented by 2.00 g, we can use the equation:

moles = mass / molar mass

Substituting the given values, we have:

moles = 2.00 g / 42.00 g/mol = 0.0476 mol
