What is the formula for percent of concentration?
M = n / V M = concentration of solution in mol/L, n = moles of substance, V = volume of solution in litres (L) the formula can re-arranged to V = n / M :)
How will the specific heat capacity changes?
Answer depend on the following formula Q=mst where Q is Heat, m is mass , s is specific heat and t is rising temperature. so according to its formula , s is direct positional to Q and inverse proportional to m and t
What volume mL of a concentrated solution of sodium hydroxide 6.00 M must be diluted to 200.0 mL to make a 0.880 M solution of sodium hydroxide?
use titration formula
What is solution formula?
A solution has not a chemical formula; the solution has a composition.
What is the formula in finding the amount of heat transfered to an object?
The formula for finding the amount of heat transferred to an object is Q = mc(change in T). Q represents heat energy in J, m is the mass of the object in kg, and c is the specific heat of the material.
What is the formula for temperature when they give specific heat?
The formula to calculate the change in temperature (ΔT) when specific heat (C) and heat (Q) are given is ΔT = Q / (m * C), where m represents the mass of the substance. If the initial and final temperatures are required, then the formula can be rearranged as Tfinal = Tinitial + ΔT.
What is the formula for molarity and explain each part?
molarity (M) is the concentration of moles (n) of a solute per liters (v) of solution M=n/v
The formula Q equals mHf is used to determine the amount of heat absorbed or released by a material at its melting point. What does m and Hf stand for?
The m stands for mass and Hf stands for heat of fusion.
A 20.0ml sample of 0.800 m Hbr solution is titrated with 0.800 m NaOH solution calculate the pH of the solution after these volumes of base are added 12.5 ml 18.7 ml 20.0 ml 29.5 ml and 34.2?
Looks as if you will need to calculate the pH of the final solution. The formula you need will be [H+] = 1 x 10-6 M.
How many grams of CaCl2 are needed to prepare 2.00 l if 0.700 M CaCl2 solution?
The gram formula mass of CaCl2 is 110.99. By definition, each liter of 0.700 M CaCl2 contains 0.700 gram formula masses of the solute. Therefore, 2.00 liters of such solution contain 1.400 formula masses of the solute, or 155 grams, to the justified number of significant digits.
Why do you heat the sodium sulfate solution?
It is not mandatory to heat this solution.
How many Na plus ions are in 250 mL of 0.500 M NaCl solution?
You use the formula M= mole of solute/Liters of solution. but you are missing the moles and you need the M(molarity) so you cross multiply them and you get M(L)=moles.You plug in 0.500 M and you find 250 ml in the amount of liters which is 0.25 and you get your answer which is0.125 mol!
