Final answer:
To calculate how much greater the mass of the second coin is than the first, subtract the mass of the first coin from that of the second coin. The second coin is heavier by 10.502 grams.
Step-by-step explanation:
To find out how much greater the mass of the second coin is than the first, we subtract the mass of the first coin from the mass of the second coin. Here's the calculation:
- Mass of the second coin = 27.22 grams
- Mass of the first coin = 16.718 grams
- Difference in mass = Mass of the second coin - Mass of the first coin
- Difference in mass = 27.22 grams - 16.718 grams
- Difference in mass = 10.502 grams
The second coin is 10.502 grams heavier than the first coin. Remember that when subtracting numbers with different numbers of decimal places, the result should contain the same number of decimal places as the number with the least precision. In this case, we maintain the precision of three decimal places after the subtraction.
