I think the given is 3 g sample of NaHCO3. then if it will be reacted with an acid, it will produce H2CO3.
so the reaction NaHCO3 + HCl --> NaCl + H2CO3
mas of H2CO3 = 3 g NaHCO3 ( 1 mol NaHCO3 / 84 g ) ( 1 mol H2CO3 / 1 mol NaHCO3) ( 62.03 g / 1 mol )
mass of H2CO3 = 2.22 g H2CO3
For A:
Your longest carbon chain is 5 so it's overall a pentane
you have 2 branchings on Carbon 2 and 4; and the branchings are methyl groups
so the name would be 2,3-dimethylpentane
Give me a little on B: It's giving me some trouble
