1 mole Si = 28.0855g Si 245g Si x 1mol Si/28.0855g Si = 8.72 moles Si
What is the concentration M of a NaCl solution prepared by dissolving 3.8 g of NaCl in sufficient water to give 245 mL of solution?
Get moles NaCl and change 245 ml to 0.245 Liters. 3.8 grams NaCl (1 mole NaCl/58.54 grams) = 0.0650 moles NaCl Molarity = moles of solute/Liters of solution Molarity = 0.0650 moles NaCl/0.245 Liters = 0.27 M NaCl ----------------------

How of atoms are in 1.80 mL of mercury?
A complete answer would require specification of a temperature, but at 20C, mercury is reported to have a density of 13.5939 grams per milliliter, so that 1.80 mL would have a mass of 1.80 X 13.5939 or 245 grams, to the justified number of significant digits. The gram atomic mass, which is the mass of Avogadro's number of mercury atoms, is 200.6; and Avogadro's Number is about 6.022 X 1023. Therefore the number of atoms in the volume specified is (245/200.6)(6.022) X 1023 or 7.345 X 1021 atoms.
How many joules of energy are absorbed when 250 g Pb is heated from 25 C to 245 C?
The specific heat capacity of lead, Cg = 0.130 J g-1 K-1The specific heat capacity is a measure of how many joules of energy it takes to raise one gram of the substance one degree. Kelvin is a temperature scale that has the same graduations as Celsius (Centigrade) but starts at -273.15 below 0oC.Energy = Cg x mass x change in temperature= 0.130 x 250 x 220= 7150 J g-1 K-1or 7.15 kJ g-1 K-1
