How many grams of Na OH have been dissolved per liter of solution to make a 7.0 M Na OH solution?
To prepare a 7.0 M NaOH solution, you would add approximately 280 grams of NaOH per liter of water. This is because the molar mass of NaOH is 40 g/mol (Na = 23 g/mol, O = 16 g/mol, H = 1 g/mol), so to make a 7.0 M solution, you need 7 moles/liter x 40 g/mol = 280 g/L.
How many grams are in 280 mg?

What is the density in grams per cubic centimeter that has a mass of 1 kg and a volume of 280 cubic centimeter?
Density is given in terms of mass/volume. To convert this to grams/cc, convert 1 kg to grams and divide by 280 cc. Thus, 1 kg x 1000 g/kg = 1000g. Then 1000g/280 cc = 3.57 g/cc, or 4g/cc (1 sig fig)
Which pair of amino acid will have the highest absorbance at 280 nm?
Aromatic amino acids such as tryptophan and tyrosine will have the highest absorbance at 280 nm due to their aromatic ring structures. These amino acids have strong UV absorbance properties and are commonly used in protein quantification assays due to their unique spectral properties at 280 nm.
Why do proteins absorb light at 280 nm and what is the significance of this absorption in their structure and function?
Proteins absorb light at 280 nm due to the presence of aromatic amino acids like tryptophan and tyrosine in their structure. This absorption is significant because it can be used to quantify protein concentration, study protein folding, and monitor changes in protein structure and function.
