Answer is: <span>the maximum mass of sugar that could be dissolved in 1.3 l of water in room temperature is 2652 grams.
</span><span>The solubility of sugar in water in room temperature is 204 g/100 ml.
Make proportion, if 204 grams of sugar dissolve in 100 ml of water, than how much dissolve in 1300 ml of water:
204 g : 100 ml = m(sugar) : 1300 ml.
m(sugar) = 204 g </span>· 1300 ml ÷ 100 ml.
m(sugar) = 2652 g ÷ 1000 g/kg = 2,652 kg.

True.
Explanation:
Organic compounds can be found pure, but generally, they are in mixtures, such as the petroleum, so it is possible to the compound received be impure;
Organic compounds can be found in the three states: solid, liquid or gas. The state will depend on the molecular forces in it and its molar mass. For example, gasoline is liquid in the ambient temperature, natural gas is a gas, and the glucose is solid;
The main characteristic of the organic compounds is the presence of C and H, the other elements can or can't be in the structure: O, N, halogens, and S;
Because of the carbon can form chains, there are several million possible known organic compounds;
The spectroscopic would give some results such as composition, molar mass, and diffraction, and with these results, it would be possible to identify some chemical properties and the tests needs more identification.
<span>c. The molecules are closer together as a gas than they do as a liquid.</span>
Answer:
Molar mass and Mass
Explanation:
The relationship between mass and number of moles is given as;
Number of moles = Mass / Molar mass
Mass = 1.6 g
Molar mass of HCl = ( 1 + 35.5 ) = 36.5 g/mol
Number of moles = 1.6 g / 36.5 g/mol
Number of moles = 0.0438 mol
