Answer:
A
Explanation:
molarity=moles of solute/liter of solution
molarity=0.26/0.3
molarity=0.87molar
Answer: Mixtures you can separate are like cereal and milk. Hope that helps
Explanation: Filteration is required to separate a mixture.
So heterogeneous mixures (that contain substances with different particle sizes) can be separated with a filter.
Homogeneous mixtures are uniform in composition so they will not be able to be separated.
Watson and Crick first contribution to DNA science was they proposed the theory of the structure of DNA. Watson and Crick's model DNA In the shape of a double helix. they determined the structure of DNA, it is a double helix. DNA molecule that helped scientist better understand the structure of DNA.
