Title: What amount (in moles) of compound are in a sample of 39.2g of silicon dioxide, SiO?2 Post by: Jess8219 on May 4, 2020 Just wanted to check my answer, so would it be 0.6523g/mol?
Title: Re: What amount (in moles) of compound are in a sample of 39.2g of silicon dioxide, SiO?2 Post by: bio_man on May 4, 2020 silicon dioxide has a molar mass of 60.08 g/mol
Take 39.2g and multiply it by 1g / 60.08 mol \(39.2\ g\times \frac{1\ mol}{60.08\ g}=0.6524\ mol\) Or... simply 0.652 moles to the correct number of significant digits Title: Re: What amount (in moles) of compound are in a sample of 39.2g of silicon dioxide, SiO?2 Post by: Jess8219 on May 4, 2020 Ok Great!
