Can you solve this Chemistry Problems?(about measurement)?

Normally I would recommend taking some time off from school, but you are soooo close! I know you can do 4 more weeks! Maybe for these last 4 weeks you and your husband could work out someway to take them to their daycare so you can have some much needed study time, minus the little interruptions. And when you finish school, you'll have a better chance of getting a good job with some decent pay (hopefully, but I'm not sure what you're studying). You are doing great, just keep up your wonderful work
