what is the formula to calculate equivalent mass?
610435
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid's molar mass by the number of protons.

Equivalent weight (E) Equivalent weight unlike molecular weight is proportional mass of chemical entities which combine or displace other chemical entities. It is defined as the mass of an element/compound/ion which combines or displaces 1 part of hydrogen or 8 parts of oxygen or 35.5 parts of chlorine by mass.

To convert milligrams to milliequivalents use the formula: mEq = (mg x valence) / atomic or molecular weight. One thousand milliequivalents equals one equivalent.

Formula to Convert Kilograms – Newtons To make a change between these two units of measurement, the formula to be used is kg x 9.807 = N which is the same conversion used automatically by the kg to N conversion calculator. As an example, 2kg = 19.6N and 5kg = 49N.

Q = m*s*dT, where Q = heat, m = mass, s = specific heat, and dT is the change in temperature (T2 - T1). You can use this formula to calculate the specific heat.

The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms. The Newton is the SI unit for weight, and 1 Newton equals 0.225 pounds.

It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.

Summary. Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.

The gram formula mass (GFM) of a substance is known as the mass of one mole. Relative atomic masses of selected elements can be found in the SQA Data Booklet. These can be used to calculate the gram formula mass of a substance.

You want your q to be in units of Joules or kJ. If you used the q=mC(delta T) with your given C, your q would be in units of (grams)(kJ). In the problem, you were given the heat capacity, not the specific heat capacity. Therefore, you don't need mass to calculate q.

It is based on equivalent weight. Equivalent weight is measure of mass proportion of an element, compound or ion in which it combines with the mass of other chemical entities. Mass of one gram equivalent, like its mole counterpart, is equal to mass in gram, which is numerically equal to equivalent weight.

The mass can be calculated by dividing the net force acting on an object by the acceleration of the object. When talking about net force, we use the units kilogram meter per second squared. This is also known as a Newton. The units for acceleration is meters per seconds squared, and the units for mass are kilograms.

To find mass from density, you need the equation Density= Mass ÷ Volume or D= M÷V. The proper SI units for density are g/cubic cm (grams per cubic centimeters), alternately expressed as kg/cubic m (kilograms per cubic meters).

Determine mass with force and acceleration. If you know the net force on the object, and it's acceleration, you can rearrange this formula to find the mass: m = F / a. Force is measured in N (newton), which you can also write as (kg * m)/ s2. Acceleration is measured in m/s2.
