How much filtered 50% NaOH (in mL) must be added to 2.0liters of boiled deionized water to give an approximately 0.18 M solution of carbonate-free NaOH (40.0 g/mol)? Presume the density of the 50% solution is 1.0 g/mL.
Neglect the change in volume cause by addition of the 50% NaOH solution
A solution is prepared by disolving 0.60 g of nicotine (a nonelectrolyte) in water to make 12 ml of solution. The osmotic pressure of the solution is 7.55 atm at 25 celcius. The molecular weight of nicotine is HOW MANY g/mol
If a given element has a mass that is 5.81 times that oc 12 C how do I figure out the mass and the element. Do I just times 5.81 times 12.0107? Therefore it is Ga
where a is constant and -infinity
Calculate How many palladium atoms will have to be laid side by side to span a distance of 4.28 mm if The radius of a palladium atom is 137 pm.?
crystallizes in a body-centered cubic array of atoms in which the length of the unit cell's edge is 569.7 pm (10-12 m). Calculate the density of the metal in g/cm3.
on a recent trip out of the country a chemistry professor found a golden-colored metal coin at a flee market. the
Diffraction of a wave through an opening may be observed when its wavelength is comparable (to within a factor of 100) to the dimensions of the opening. Consider directing beams of baseballs and positrons onto a crystal,
the uncertainty b in some observable b is given by a formula bsqrtltb2gt-ltbgt2. use this formula to determine
a 0.831-g sample of so3 is placed in a 1.00-l container and heated to 1100 k. the decomposes to so2 and o2
Suppose that 2.00mL of isopently alcohol was reacted with excess acetic acid and that 2.00g of isopentyl acetate was obtained as product. Calculate the percentage yield.
A 195mg sample of a non-electrolyte isolated from throat lozenges was dissolved in enough water to make 10.0mL of solution at 25 degrees Celsius. The osmotic pressure of the resulting solution was 4.83atm. Calculate the molar mass of the compound.
Suppose A 5.0mL sample of vinegar was titrated with 7.2mL of 0.55 M NaOH(aq). If the density of the vinegar solution is .00 g/mL, explain what is the mass percent of acetic acid present
