How many mg will 2.38×10–5 moles weigh?

Answer 1

To answer this question, we need to use the molecular weight of the substance in question. Let's assume we are given the molecular weight as 100 g/mol.

First, we can convert the number of moles to grams using the molecular weight:

2.38×10–5 mol x 100 g/mol = 2.38×10–3 g

Next, we can convert grams to milligrams:

2.38×10–3 g x 1000 mg/g = 2.38 mg

Therefore, 2.38×10–5 moles of a substance with a molecular weight of 100 g/mol would weigh 2.38 mg.
