Silver is not a compound. It's a mixture
Percent yield = (Actual Yield/ Theoretical Yield) x 100
Given, Actual Yield of silver = 410 grams
Given, mass of copper = 127 g
Atomic mass of copper = 63.546 amu
Formula: Moles = mass / atomic mass
Moles of copper = 127 g/ 63.546 amu = 1.998 mol
Based on the given balanced chemical reaction, the molar ratio between Cu: Ag is 1:2
So 1.998 mol of copper should yield (2 mol Ag/ 1 mol Cu) x 1.998 mol of Cu = 3.996 mol
Calculated mol of Ag = 3.996 mol
Atomic mass of silver = 107.8682 amu
Mass of silver = moles x atomic mass = 3.996 mol x 107.8682 amu = 431 g
Based on the math, the theoretical yield = 431 g
Percent yield of silver = (410g/431g) x 100 = 95. 13%
The answer is 95. 13%
Answer:
No
Explanation:
The solubility of a solid in water refers to the amount of that solid that dissolves in water.
It is not possible to calculate the solubility of the solid because the student threw away the first precipitate that formed. We already have the volume of water, but having lost some mass of precipitate, it has become impossible to accurately determine the solubility.
Hence the answer provided above.
Answer:
Volume
Explanation:
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contains.[1] Volume is often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container; i.e., the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces. Three dimensional mathematical shapes are also assigned volumes. Volumes of some simple shapes, such as regular, straight-edged, and circular shapes can be easily calculated using arithmetic formulas. Volumes of complicated shapes can be calculated with integral calculus if a formula exists for the shape's boundary. One-dimensional figures (such as lines) and two-dimensional shapes (such as squares) are assigned zero volume in the three-dimensional space.
The volume of a solid (whether regularly or irregularly shaped) can be determined by fluid displacement. Displacement of liquid can also be used to determine the volume of a gas. The combined volume of two substances is usually greater than the volume of just one of the substances. However, sometimes one substance dissolves in the other and in such cases the combined volume is not additive.[2]
In differential geometry, volume is expressed by means of the volume form, and is an important global Riemannian invariant. In thermodynamics, volume is a fundamental parameter, and is a conjugate variable to pressure.
