Answer: The second law of newton states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and also the mass of the object.
There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We do as follows:
0.24 g (1 mol / 342.3 g) (
6.022 x 10^23 molecules / 1 mol ) =4.222 x 10^20 molecules
