To find the volume, we must first make sure that each of the dimensions is in the correct units before we make the calculation. Since we want cubic meters, and every dimension is in meters, we are good to go in this case.
So to solve for the volume, we must multiply each of the sides together:
If the answer must be in significant figures, then we know that we must only use two significant figures in this case, and so the volume would then be .
Answer:
The solubility of methylacetylene is 0,11 g L⁻¹
Explanation:
Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid.
The formula is:
C = kH P
Where C is solubility of the gas (In mol/L)
kH is Henry constant (9,23x10⁻² mol L⁻¹ atm⁻¹)
An P is partial pressure (0,301 atm)
Solving, C = 2,78x10⁻³ mol L⁻¹. In grams per liter:
2,78x10⁻³ mol L⁻¹ₓ = <em>0,11 g L⁻¹</em>

<u>Answer:</u> The amount of kilocalories contained in the given serving of soup is 0.137 kCal
<u>Explanation:</u>
<u>As per the USDA:</u>
Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.
We are given
Mass of fat in the soup serving = 5.0 g
Mass of carbohydrates in the soup serving = 20.0 g
Mass of protein in the soup serving = 3.0 g
Conversion factor used: 1 kCal = 1000 Cal
Applying unitary method:
1 gram of fat provides 9 calories
So, 5.0 gram of fat will provide =
1 gram of carbohydrates provides 4 calories
So, 20.0 gram of carbohydrates will provide =
1 gram of proteins provides 4 calories
So, 3.0 gram of fat will provide =
Total kilocalories per serving = [0.045 + 0.080 + 0.012] kCal = 0.137 kCal
Hence, the amount of kilocalories contained in the given serving of soup is 0.137 kCal
