Molar mass is related to mass percentage, and it is used to calculate the ratio between the mass of a certain quantity of a substance to the number of moles of that substance. It is similar to a density value. To calculate the the molar mass of the compound, we take the mass of solu...
for convenience, specify the amount of solute in terms of moles. Each mole contains 6.022 × 10^23 particles, and the mass of a mole of particles is the sum of the atomic weights of its elements. To find the concentration of a solution, you need to know the formula and mass of its ...
How to use a balance to find the mass of an object? Explain. Measurement: Measurement is a way to determine the magnitude of a desired trait of a given object. These traits include the mass of an object, the volume of an object, temperature, and time. Answer and Explanation: ...
Osmosis is a process in which the solvent molecules move from a lower concentrated area to a higher concentrated area through a semi-permeable membrane. Osmotic pressure is a pressure applied to stop osmosis. Osmotic pressure is calculated by multiplying the vant Hoff fa...
Ounces and grams are two common units used to measure weights in small quantities. Ounces commonly are used in the United States, where the main unit of measurement for weights is the pound. An ounce is 1/16 of a pound. Grams are the main base of measure
The Avogadro's number is the number of particles in one mole of a substance. The particles can either be atoms, ions or molecules. The molar mass is the mass of one mole of a substance.Answer and Explanation: Step 1: Use the molar mass of C4H10 to determine the moles in ...
Molar Solution: The term "molar solution" refers to the corresponding molarity of a solution. For example, a two molar solution means the molarity of the solution 2 mol/L. Alternatively, it suggests the existence of two moles of solute in one liter of the solution....
n = number of moles (which is related to the mass of the gas, i.e. 1 mol = 6.023x1023 molecules of the gas, and n = mass (in grams)/molar mass(MM)), R = the ideal gas constant, and T = the absolute temperature.What...
n = number of moles of gas m = mass of gas MM = molecular mass of the gas This is helpful since we needed to find the mass and we know the molecular mass of oxygen gas. If we substitute for n in the first equation, we get: ...
The ability of a restriction enzyme to find a single site by linear diffusion in the supercoiled plasmid is also presumed to be different than for any of the sites on a linear substrate. Although it is not common, some enzymes exhibit differences in their ability to cut supercoiled DNA ...
