The total mass of the original tissue were from the source which are the pig ovaries. But first, convert 5.6 tons to mg.
5.6 tons × (1000 kg/1 ton) × (1000 g/1kg)×(1000 mg/1g) = 5.6 x 10^9 mg
Thus, the percentage of estrone in the original tissue is
(12.0 mg /5.6 x 10^-9 mg) x 100 = 2.14 x 10^-7 %
Answer:
There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease. Point mutations are the most common type of mutation and there are two types.
Explanation:
First is to calculate the mass of required for the 0.50 M ammonium carbonate. assuming ammonium carbonate is 100 % pure
m = 0.5 L ( 0.50 mol ammonium carbonate / L) ( 96.09 g ammonium carbonate/ mol ammonium carbonate)
m = 24.0225 g ammonium carbonate
1. weigh 24.0225 g ammonium carbonate
2. place it in a 500-ml volumetric flask
3. add water to volumetric flask up to the line.
4. placed the cap and then shake properly.
The first one and last one I think
