How many moles of silicon, si, are in 1.75 * 1024 si atoms?

In the molecule ClF5, chlorine makes five covalent bonds. Therefore, five of its seven valence electrons need to be unpaired. The orbitals with the same energy are known as degenerate orbitals.

How many grams of Ca (NO3) 2 are needed to make 25.0 g of a 15.0% Ca (NO3) 2 (aq) ?

Nick and Kel reacted 2.80 g of NiCl2· 6 H2O with 7.00 mL of 4.00 M C2H8N2. They recovered 2.40 g of product, [Ni (C2H8N2) 3] Cl2. At the end, the filtrate was a dark blue solution.

I am studying for ACS and have trouble understanding how to rank molecules in decreasing or increasing solubility in water ... I know the rules of which molecules are insoluable ... But how do you rank them in which is least or most soluble.

Water interacts with polar substances like - OH groups but not with non-polar substances like methyl (-CH3) or ethyl groups (-CH2). Using this information, select the molecules that will easily dissolve in water based on polarity not on size.
