One way to speed up the solution process is to break down the problem into smaller, more manageable parts. Another way is to implement more efficient algorithms or strategies to tackle the given problem.
Number of moles = Mass of the sample in g/Molar mass in g

Very high speed is the best speed to separate a soil sample in a centrifuge.
first measure the volume of the sample solution needed to change the blue color of the DCPIP solution into colourless. then, weigh the mass of the sample solution. finally calculate the concentration by using the formula: volume required t change the color of DCPIP solution (dm) per mass of the sample solution (g)
Yes, the density of an entire solution can be estimated through the measurement of a small sample. By accurately measuring the volume and mass of a small sample, you can calculate the density of the entire solution using the formula Density = Mass/Volume.
sample of problem solving
It is a solution.
For every problem there is a solution to the problem, just as you can have a key to a lock.However for a problem you have a special solution for the problem just as you have a key made for a particular lock.
Graphical method sample problem: Find the solution to the system of equations: 2x + 3y = 12 x - y = 3 Analytical method sample problem: Solve the system of equations using substitution method: 3x + 2y = 11 4x - 5y = -7
