<span>You know how when you dilute something, you would divide by the volume, and when you take an aliquot, you would multiply by the volume? Well, since you're working backwards, you do the opposite operations.
3.17E-6 M (150.0 mL / 10.00 mL) = 4.76E-5 M (150.0 mL / 10.00 mL) = 7.13E-4 M (150.0 mL / 10.00 mL) = 1.07E-2 M (150.0 mL / 10.00 mL) = 0.160 M
So the original stock was a 0.160 M HBr solution.</span>
Answer and Explanation:
The primitive atmosphere of Earth may have favored the abiotic synthesis of organic molecules because it **had close to no oxygen, hence, it was powerfully reducing. It had pure energy sources too in form of ultraviolet rays from the sun (it was extremely hot! Too hot for water in liquid form to exist in fact!), outgassing from the numerous volcanoes and lightning**.
Abiotic synthesis means a formation reaction where the reactants are charged to become products, almost all on their own, with no catalyst especially.
So, these factors would have helped the organic molecules to form as most of what is needed to overcome the energy barrier and become products.

Answer:
Volumes can have the same volume but different masses if they have different densities. For example, a 10 x 10 x 10 block of lead has the same volume as a 10 x 10 x 10 block of pine wood, but the lead block weighs 22.6 times more than the pine block. Indeed, the density of lead is high enough that the lead block will sink in water, whereas the pine block's density is low enough that the pine block will float in water.
Volume is a measurement, the units are cubic metres or cubic centimetres. Litres = 1000 cm3
Mass is a measurement, the units are grams, kilograms.
^^^^^^^^^^^^^^^^^^
to that answer.
Mass is not weight. it is the amount of matter an object takes up. Therefore, saying that a lead block weights 22.6 times more than the pine block does not answer how an object can have different masses but the same volume. :D
