Figure 1. Sugar is one of many components in the complex mixture known as coffee. The amount of sugar in a given amount of coffee is an important determinant of the beverage’s sweetness. (credit: Jane Whitney) Solutions We have previously defined solutions as homogeneous mixtures, meaning tha...
which essentially means businesses don't have to go through the rigmarole of redesigning their facilities in order to accommodate these new workers. Just like humans, the bots work full eight-hour shifts and even recharge themselves during their downtime, meaning the age of worker robots doing th...

The correct formula of Molarity can only be determined when you know the proper definition of the term and the meaning of all the other chemical terms used to build the formula. As per the definition, the molarity of a solution is the total number of moles of solute present in a particula...
Calculate the molarity (M) of the following 6.05 g of NaCl in 500.0 mL of NaCl solution. What is the molarity of 1.83 mg of HCl in 0.075L of solution? What's the concentration meaning of the following solutions? Explain how to prepare them. a) sulphuric acid 1+1 b) sulphuric aci...
Why is measuring mass important in chemistry? Define the term electrolyte. What do you mean by calibration? What is the meaning of escape velocity? What is the definition of gravity? How many milliliters of a 0.45 M of BaCl2 solution contains 15.0 g of BaCl2?
Stating the molar volume of a gas without indicating the reference conditions of temperature and pressure has very little meaning and can cause confusion. 在不指明温度和压力条件的情况下,说明气体的摩尔体积几乎没有意义并且可能引起混淆。 LASER-wikipedia2 The hydrogen-storage material is mainly forme...
“mono” meaning one and “chromate” meaning color) and an additional exit slit. The separation of white light into different colors (wavelengths) is known as diffraction. The selected light then reaches the sample and depending on how the light interacts with the chemical compound of interest,...
Did you know that ppm is used in different ways depending on the context? When dealing with dilute solutions, 1 ppm can be approximated as 1 mg1 mg of substance per liter of water, or 1 mg/L1 mg/L. On the other hand, molarity is molar concentration, meaning that it tells you how ...
We have previously defined solutions as homogeneous mixtures, meaning that the composition of the mixture (and therefore its properties) is uniform throughout its entire volume. Solutions occur frequently in nature and have also been implemented in many forms of manmade technology. We will explore ...
