Answer given14.1 mol
The answer is 0.0709 mol0 / 1

Joe has been a great tutor and has really helped me improve my understanding of chemistry. He explains difficult topics in a clear and simple way, making them much easier to understand. His lessons are always well structured and he gives helpful advice on both revision and exam technique. He's patient, supportive, and always willing to go over anything I'm unsure about, even if it means explaining it several times. Thanks to his help, I've become much more confident in chemistry and would highly recommend him to anyone looking for help with chemistry.
