The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
To calculate the hydrate form from moisture, you first need to determine the moisture content of the substance. Then, you can use this information to calculate the hydrate form by accounting for the amount of water molecules present in the substance due to moisture. This can be done by converting the moisture content to a molar ratio and then determining the hydrate form based on the known chemical composition and molecular weight of the substance.
Please I need this to be answer as soon as possible
It is a problem where you need to calculate percents.
The most important thing for your to remember is that in a physical change the composition of a substance does not change and in a chemical change the composition of a substance does change.
33/36 x 100 = 91.67% To calculate a percentage, all you need to do is: x/y x 100 easy!
Density = Mass/Volume so you need to measure the mass of the substance and divide by the volume that it occupies.
To calculate the density of a substance, you need to know its mass and volume. Density is calculated by dividing the mass of the substance by its volume, expressed in units such as grams per cubic centimeter (g/cm3) for solids and liquids.
To calculate 1 millimolar (mM) concentration of a substance, you need to know the molar mass of the substance. Then, divide 1 millimole (mmol) by the molar mass to obtain the volume of the substance needed to make a 1 mM solution.
You need to know the density of the substance being measured.
you need to quote the circumference to calculate the length of the arc or its percentage
To calculate heat energy when you know volume and temperature, you would need to use the formula Q = mcΔT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. Given volume, you would also need to know the density of the substance to calculate the mass.
To calculate the amount of heat absorbed as a substance melts, you do not need information about the substance's boiling point or its specific heat capacity in the liquid state. The key parameters needed are the substance's heat of fusion (melting) and the mass of the substance melting.
