Finally, useAvogadro's numberto determine the number of molecules in a drop of water. Avogadro's number tells us there are 6.022 x 1023molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles:...
1 mL of water = 1 gramAvogadro's Number:The Avogadro's number is the number of particles (molecules or atoms or ions or even photons) that are contained in one mole of a substance. It is equal to {eq}6.023 \times 10^{23}\;\text{...

Answer to: How many nitric acid molecules are in 4.20 grams of HNO3? By signing up, you'll get thousands of step-by-step solutions to your homework...
Avogadro's number (6.022 x 10^23) is a collective number which tells you how many molecules of a substance there are in 1 mole of that substance. With the molar mass, this allows you to convert between mass, moles and molecules. With Avogadro's number yo
To deal with this issue, scientists came up with a way to standardize talking about how many atoms or molecules are reacting in a given situation. The mole (abbreviation mol) is the SI unit for the amount of a substance. It is defined as about 6.022 x 1023 atoms or particles or things...
Finally, we examine how changes in curvature can influence transcriptional regulation through a reorganization of cytoskeletal forces acting on the nucleus, thereby facilitating the development of specific human diseases. Key points Cells interact with the curved surfaces of many organs and, at a lower...
γδ T cells constitute a sizeable and non-redundant fraction of the total T cell pool in all jawed vertebrates, but in contrast to conventional αβ T cells they are not restricted by classical MHC molecules. Progress in our understanding of the role of γδ T cells in the immune system...
How many molecules of molecular chlorine, Cl_2 are in 0.00245 mol of Cl_2? How many moles are in 23.8 grams of sodium chloride? How many moles are in 25.0 grams of sodium chloride? How many moles are in 24.0 grams of sodium chloride? How many moles of chlorine are needed to react ...
Assume that oxygen is the excess reactant in this reaction. If I have 2.5 L of propane at STP, how many grams of water can be produced by this combustion? If 5.0 moles of propane react in excess of oxygen, how many molecules of water will be formed? A. 3.0 \t...
