Yes, but the dating is only off a little (500 years or so).

How much of one gram of radium-226 will remain unchanged after four half-lives?
After each half-life, half of the radium-226 will decay. Therefore, after four half-lives, 1/2^4 or 1/16th of the original gram of radium-226 will remain unchanged. This means that 1/16th of a gram, or 0.0625 grams, will still be unchanged after four half-lives.

What is the decay constant for an isotope of carbon14 that has an activity of 6103 disintegrations per minute when first measured and 4103 disintegrations per minute four hours later mol wt14gmol?
That is completely unrealistic. C-14 has a half-life of several thousand years, not a few hours as implied in this example. Anyway, to solve this in general you can write the exponential equation: N = N0e-λt where N is the remaining amount, N0 is the original amount, λ is the decay constant, and t is the time. Replace the numbers you know, and solve for λ. Note that the "disintegrations per minute" are proportional to the amount of remaining substance, so you can just as well assume that those numbers represent the remaining amount.
An artifact is found that some are claiming is 11100 years old A laboratory analysis shows that approximately 26 percent of the original carbon-14 is present The half-life of carbon-14 is 5730 year?
Yes, but the dating is only off a little (500 years or so).
