The density of hydrogen chloride, HCl, is 1.490 g/mL. Calculate the volume occupied by 5.655 moles of hydrogen chloride.

Question

I've tried it a couple times to double check but the hints on my homework are not helping. Due tonight (FEB 8) at 11:59pm if anyone can help explain. :)

Answer 1

Hey Miranda! Not sure if you are looking for a detailed explanation or just a quick answer to submit for your homework but I'm here to help:) please excuse the formatting on this because I am typing on my computer.

1. Convert moles to grams. We are doing this because we are given density in terms of g/mL.

5.655mol x (36.458g/ 1 mole HCl) = 206.169g HCl

2.Now use this number and cancel out the grams

206.169g HCl x (1mL/1.490g HCl) = 138.36 mL of HCl which is the volume.

I hope this helps. Let me know if you need any deeper explanation for this question
