Hello,

I just started my grad school and they assigned some chem questions to brush up on our skills.  I really forgot how to answer these questions and I would really appreciate if someone could help me out.  I don't need the answers, I just want to understand how to do them.  Thank you for your *delete me*!!

1. Describe how you would make a 400 ml solution of a 20% w/v sucrose solution. MW of sucrose = 342.3

2. Given a 1M TrisHCl pH 8.0 and 0.5M EDTA solution, how would you make 50ml of a TE solution (10mM TrisHCl pH 8.0 and 1.0mM EDTA).
