The number of grams of agarose that you need to make 200 ml of 2% agarose gel is 4 grams
calculation
number of grams is calculated using M/v x100 =% m/v formula
M (mass) =?
V(volume) = 200 ml
%(M/V) = 2%
convert the 2 % M/V into fraction = 2/100
then substitute the values into the equation
= M/200 ml = 2/100
multiply both side by 200
M is therefore = 2/100 x200
M=4 grams
The soda has been exposed to oxygen. Therefore, a chemical reaction is taking place.
239.0 g/mol
Add the mass of each individual atom
Answer:
solids have definite shape and volume. liquid have definite volume but not definite shape. gases do not have definite volume as well as definite shape.
For C, they would be the same. At the equivalence, you have equal moles of both the acid and the base.
