While adding two numbers, the rule of significant figures requires that the number of decimal places in the final answer is equal to that of the term with the least decimal places
In the given examples:
1) 0.09 - has 2 decimal places
1.324- has 3 decimal places
Sum = 0.09 + 1.324 = 1.414
Round off to 2 decimal places = 1.41
2) 41.0 - has 1 decimal place
78.3- has 1 decimal place
Sum = 41.0 + 78.3 = 119.3
Final answer will also have 1 decimal place = 119.3

<h3>Pressure has additive properties meaning that if you add the partial pressures together, you obtain total pressure. P total = P1 + P2 + P3 + ... Pressure of container = pressure of H2 + Pressure of N2 + Pressure of F2 = 3atm + 2atm + 5atm = 10atm Hope that helped. ;)</h3>
