The linear mass density formula is mass per unit length, denoted by (lambda) and calculated as mass divided by length. It is used to find the mass of a one-dimensional object by dividing its total ...
To find the percentage mass of one of these elements, divide the molar mass of the element by the total molar mass of the compound (add them all up, using oxygen three times), then multiply by 100%.
How do you work out the number of moles of unknown compound if you are only given the molar mass? To find the number of moles from molar mass, divide the mass of the compound by its molar mass.
To find the density of a liquid, you need to measure its mass and volume. The formula for density is density mass/volume. First, measure the mass of the liquid using a scale.
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 ...
To find the mass of an element in a chemical compound, you first need to determine the molar mass of the compound by adding up the atomic masses of all the elements present.
The molar mass of MgCl2 is 95.21 g/mol. Then, divide the given mass by the molar mass to find the number of moles, and finally, use Avogadro's number (6.022 × 10^23) to convert moles to formula ...
To calculate the friction force on an object, you can use the formula: Friction force mass x acceleration. This formula helps determine the force resisting the object's motion due to friction.
The mass of an object depends on its density. To find the mass of 3.75 cm3 of a substance, you need to know the substance's density. The formula to calculate mass is Mass = Density x Volume.
