May 15, 2017 · In your case, you would have zinc-66, a nuclide of zinc that has a mass number equal to 66. Now, an atom's mass number, A, tells you the number of protons, which is given by the atomic …

You get the new concentration from a standard dilution calculation. c1V 1 = c2V 2 c2 = c1 × V 1 V 2 = 0.35 mg/mL× 15.0µL 30.0µL = 0.175 mg/mL Step 3. Calculate the mass of protein loaded on the gel …

Feb 17, 2017 · All I have done is to take the atomic masses from the Periodic Table, and added them together appropriately. You are not expected to remember any of the atomic masses (tho' a few will …

You plan to make 35 fluid ounces of sauce. How many fluid ounces of tomato paste do you need? What is the trend in ionization energy as atomic number increases within alkali earth metals, halogens, and …

The Carbon-12 atom is used as the basis for standard atomic weights. Published values for atomic weights are actually weighted-averages of all of the isotopes, so none of them will be exactly the …

May 21, 2015 · This is because an electron changes the proton to one less so Iodine which has an atomic number of 53 will change to atomic number 52, which is Te. And of course the mass number …

What is a unified atomic mass unit? How is it equivalent to 1 g/mol? Does a moving massive object have more kinetic energy than a lighter object? What is the number of molecules in 1.00 mol of iodine …

An electric toy car with a mass of #3 kg# is powered by a motor with a voltage of #4 V# and a current supply of #2 A#. How long will it take for the toy car to accelerate from rest to #14/3 m/s#?

The final temperature depends on the mass of the water, and the mass must be sufficient that the water does not boil. But we can do a general calculation.

In this problem, the mass unit is grams, and the volume unit is "cm"^3. The density formula is: "density" = "mass"/"volume" Your question is asking you to find the mass of a sample of silver with a known …
