Answer:
Explanation:
Hello,
In this case, the unit of concentration is molality which is defined by:
Whereas the mass of the solvent is measured in kilograms. In such a way, with the given data, we first compute the kilograms of water:
Then, we solve for the moles of the solute:
Finally since the molar mass of ethanol is 46 g/mol, we compute the grams for the given solution:
Best regards.
Answer:
P₄O₆
Explanation:
The molecular formula is a whole number multiple of the empirical formula. that is, if the mole wt is 219.9 gms/mole and the empirical formula weight is 110 gms/mole*, then the whole number multiple is 219.9/110 = 2 => Molecular formula => (P₂O₄)₂ => P₄O₆.
They share the same number or protons
7.42 moles of Ag(PO4)2 x 297.8109g / 1 moles = 2210g Ag(PO4)2
The electricity on which the motor runs represents ATP.
ATP, adenosine triphosphate, is the energy currency of the cell. The energy released during the process of respiration is stored in the ATP molecule, and the ATP is stored within cells. Whenever the cell requires energy for any function, it simply hydrolyzes the ATP molecule, breaking a phosphate group off and releasing energy in the process.
