it is the mass of an object
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 :)
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
use titration formula
A solution has not a chemical formula; the solution has a composition.
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.
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.
molarity (M) is the concentration of moles (n) of a solute per liters (v) of solution M=n/v
The m stands for mass and Hf stands for heat of fusion.
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.
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.
It is not mandatory to heat this 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!
