You can figure this out. Determine the molecular weight of glucose- that is the weight in grams of 6.02x10^23 molecules (one mole of glucose). Then weigh one sugar cube- that is the weight of your unknown number of molecules. Divide your sugar cube weight by the molecular weight- that gives you the percentage of a mole that your sugar cube contains.
HIV is the cause of the spectrum of disease known as HIV/AIDS. HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells.
The human immunodeficiency virus (HIV) infects cells of the immune system, destroying or impairing their function. Infection with the virus results in progressive deterioration of the immune system, leading to immune deficiency. The immune system is considered deficient when it can no longer fulfil its role of fighting infection and disease.
