A beaker has a mass of 77.275 calculate this mass in mg

Rainbow [258]2 years ago

By definitions of the prefixes in the metric system, the prefix milli- (abbreviated as m as in mg) indicates 1/1000 or 1 x 10^-3 of a gram. In this case, if a beaker has a mass of 77.275 g (I am assuming this is grams since most other units would make it too heavy or too light), we would multiply this by 1000 to convert it to milligrams. So 77.275 g = 77,275 mg.

Copper has an atomic number of 29 and a mass number of 64. what would result if an uncharged copper atom lost two electrons?
nikklg [1K]

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 Cu^{2+} which can be represented as follows:

Cu_{29} ^{64}→Cu^{2+}

The shape of a liquid's meniscus is determined by __________. the viscosity of the liquid the type of material the container is
Tanya [424]

In the case of the liquid meniscus, a concave meniscus that is what one usually observes takes place when the molecules of the liquid are fascinated towards the container. This takes place with water and a glass tube. A convex meniscus takes place when the molecules exhibit a stronger attraction with each other in comparison to the container, as in the case of glass and mercury.  

The shape of the liquid meniscus is determined by the relative magnitudes of the cohesive forces in the liquid and adhesive forces between the liquid and its container.

How many equivalents are in a solution that contains 0.25 moles Mg2+ and 0.50 moles Cl–?
Vinil7 [7]

Answer:

Explanation:

Mg²⁺ is divalent , hence

Molecular weight / 2 = equivalent weight .

.25 moles = 2 x .25 equivalents = .5 equivalents .

Cl⁻ is monovalent so

molecular weight = equivalent weight

.50 mole = .50 equivalent

Total equivalent = .50 of Mg²⁺ + .50 of Cl⁻

= 1 equivalent .

(01.01 MC)
lys-0071 [83]

The answer would be option B "I believe there is life on other planets." Scientific statements have a possibility to be wrong. It's not option A because option A is a opinion. It's not option C because option C is a fact. It's not option D because option D is a opinion.

Hope this helps!
