In order to get the sum of 2.7 and 2.47, we will add both numbers. So, 2.7 plus 2.47 would be 5.17. And the correct number of significant digits in this number is still the same, 5.17, so we have three significant numbers. Why? There are three rules in identifying the significant figures: 1. Non zeros are always significant (which this applies in our sum above). 2. Any zeros in between significant numbers are always significant. 3. <span> The final zero or zeros in the decimal portion only are significant.</span>

Answer:
Explanation:
Remember that
To convert L to mL multiply by 1,000
we know that
Gina made 9,350 mL
She packed 1.8 L of the soup in her kids' lunches
She froze the rest of the soup
step 1
Convert L to mL
step 2
To find out how many milliliters of soup did Gina have left to freeze, subtract 1,800 mL from 9,350 mL

The new volume of a gas at STP that occupies 16L of space is 27.43L.
<h3>HOW TO CALCULATE VOLUME?</h3>
The volume of a given gas can be calculated using the following expression:
P1V1/T1 = P2V2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
- T1 = initial temperature
- T2 = final temperature
1 × 16/273 = 2.6 × V2/468
16/273 = 2.6V2/468
0.0586 × 468 = 2.6V2
V2 = 27.43
Therefore, the new volume of a gas at STP that occupies 16L of space is 27.43L.

Well, atoms are neither created nor destroyed. Therefore, they are redistributed resulting in change in the molecular composition of substances.
