How many chlorine atoms are there in four phosphorus trichloride molecules express your answer as an integer?
Phosphorus trichloride (PCl₃) contains three chlorine atoms per molecule. Therefore, in four molecules of phosphorus trichloride, the total number of chlorine atoms is 4 molecules × 3 chlorine atoms/molecule = 12 chlorine atoms. Thus, there are 12 chlorine atoms in four phosphorus trichloride molecules.

How do you express Cl as an integer?
To express chlorine (Cl) as an integer, you can use its atomic number, which is 17. This indicates that a neutral chlorine atom has 17 protons in its nucleus. In terms of its most common ion, Cl⁻, it has gained one electron, but the integer representation remains the atomic number 17. Therefore, Cl can be represented as the integer 17.
What is the most appropriate to express number of molecules per volume?
Avogadro's number is the number of molecules in a mole of a substance. This is expressed as 6.022 141 29 E23 /mol. This is defined as the number of atoms in 12 grams of carbon12. A mole of any gas has this number of molecules. Any fraction of that mole must be divided into the number.

Do T cells express MHC II?
No, T cells do not express MHC II. MHC II molecules are primarily found on antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and are involved in presenting antigens to T cells for immune responses. T cells, on the other hand, express MHC I molecules, which present antigens to other immune cells.

How to express 0.00001 ppm in molecules per centimeter cubed?
To convert parts per million (ppm) to molecules per cubic centimeter, you need to know the molecular weight of the substance. Use Avogadro's number (6.022 x 10^23) and the formula: molecules/cm^3 = (ppm * density * 6.022 x 10^23) / (molecular weight * 10^6). This will give you the concentration of molecules per cubic centimeter.
What is the prefix for express?
There is no suffix in express. Ex- is the prefix in express.
