The answer is D, because "Animals without a backbone are invertebrates."
Answer:
22.46
Explanation:
.There are 3.79 liters in one gallon
Answer:- 544.5 mL of water need to be added.
Solution:- It is a dilution problem. The equation used for solving this type of problems is:

where,
is initial molarity and
is the molarity after dilution. Similarly,
is the volume before dilution and
is the volume after dilution.
Let's plug in the values in the equation:



Volume of water added = 907.5mL - 363mL = 544.5 mL
So, 544.5 mL of water are need to be added to the original solution for dilution.
From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.
<h3>What is molarity?</h3>
The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where
- C = concentration
- k = constant
- p = pressure
C = 0. 0354 * 10^-3 g/28 g/mol × 1000/1 L
C = 0.0013 M
k = C/p = 0.0013 M/1 atm
k = 0.0013 Matm-1
Now;
C = 0.0013 Matm-1 * 2 atm
C= 0.0026 M

Answer:
6.3 atm
Explanation:
P2=T2P1/T1
Change C to K
We can check this by knowing that P and T at constant V have a proportional relationship; Hence, this is correct.
