Note that the prime factorisation of 2501 is: 2501 = 41 ⋅ 61 With no square factors, the square root cannot be simplified. Note that 502 = 2500 so √2501 will be an irrational number a little more …

Then, we can just find the mass of 2.272 carbon atoms by multiplying 2.272 by the mass of 1 mole of carbon: 2.272 xx 12.01 = "27.29g" Since there was 1 significant figure in the question, …
