Answer: The sample that contains the greater number of molecules is water.
Explanation: To calculate the number of molecules, it is used the Avogadro's number ( 
particles/molecules). So, considering that the mass to water and carbon dioxide is 1g (it can be any other number), the relationship between moles and molar weight is:
To water: 
= 0.05 moles.
Therefore,
1 mol ---- molecules
0.05 moles ---- x
x = 
molecules of water.
To carbon dioxide: 
= 0.02 moles.
Therefore,
1 mol ---- molecules
0.02 moles ---- y
y = 
molecules of carbon dioxide.
Answer:
The final temperature of the water will be 328.81 K .
Explanation:
Using the equation, <em>q = mcΔT</em>
here, <em>q = energy</em>
<em>m= mass</em>
<em>c= specific heat capacity </em>
<em>ΔT= change in temperature</em>
<em>Mass of water = 1kg (1000 g ) per liter</em>
<em>∴ 6.2 Liter of water = 6200 g</em>
<em>c of water ≈ 4.18 J /g/K</em>
<em>Now, </em>
<em>980000 = 6200*4.18*ΔT</em>
<em>ΔT = 37.81 K</em>
<em>∴ final temperature of the water = 291 + 37.81 = 328.81 K</em>
