Based on the given molecular formula, the molar mass of ethylene glycol is 62 g/mol. We solve for the number of moles of the solute,
n = (7.1 kg)(1000 g/ 1 kg) / 62g/mol = 114.52 mol
Then, we divide this value by the given mass of the water in kg
m = (114.52 mol) / 1.2 kg = 95.43 m
Thus, the molality of the substance is approximately equal to 95.43 m.
Answer:
Carbonated water is a mixture,
Explanation:
which means it contains two or more different chemicals.
Is Sodium Hydroxide an element, mixture, or compound?
An example would be placing sodium (Na) in water (H2O). Sodium creates a new chemical bond producing a new substance with new physical and chemical properties known as sodium hydroxide (NaOH). So, if a new chemical formula must be written after two or more substances combine it is not a mixture.
The statement "<span>All gaseous mixtures are solutions." is true. This is because there are a number of gaseous molecules present in a volume of gas and they are considered solutions.</span>
Hydrogen and Helium cannot bond together. Put aside the inertness of helium (or all noble gases), bond formation is only favored when the final state of the two elements is more stable than their initial state. ... Helium compounds has some predictions though none of them contain only those two elements.
Answer:
Entropy,mass and volume.... I think
