Answer:
Molarity of solution = 0.727M
Explanation:
Molarity of solution is defined as moles solute per Liter of solution. For the posted problem use M = n/V where n = moles of solute and V = Liters of solution. That is ...
n = 58.9g/180.16g·mole⁻¹ = 0.327 mole (3 sig. figs.)
V = 450.0ml/1000ml·L⁻¹ = 0.450L (3 sig. figs.)
∴ Molarity = n/V = 0.327mole/0.450L = 0.727mol/L = 0.727M
Answer:
four 0.5 times 10 to the 23rd Adams of Neptune
Explanation:
The atomic mass of an element is the number of times of an atom of that element is heavier than an atom of carbon taken as 12. In simpler way, atomic mass is number of protons present in nucleus of an atom, which is a characteristic of an chemical element and is determines place of the element in the periodic table. Mass number is total number of protons and neutrons. If an uncharged atom looses electron from its outermost shell, it becomes cation, which is positively charged species. Atomic number and mass number do not change if electron goes out of an atom.
Uncharged copper after loosing two electrons is converted to 
which can be represented as follows:
→
Allene (1,2-propadiene) has point group D2d, itself is achiral because it has two planes of symmetry. ... An allene with substituents on one terminal carbon atom are unlike and substituent on other terminal carbon atoms are same, allene will be achiral. It will have one symmetry plane.
Hope this helped :)
Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property. It is a chemical property.
