If the ratio of mass to volume is higher, then density is higher. If the ratio of mass to volume is lower, the density is lower.
If H+ would have to dissociate from a substance and must be the only positive ion in the solution that substance must be an acid.
CH3CHO is an aldehyde called acetaldehyde.
CH3CH2OH is an alcohol called ethanol
CH3OCH3 is an ether called dimethyl ether.
and finally, the answer CH3COOH is a weak acid called acetic acid.
Perihelion is when a planet is closest to the sun and aphelion is when it is farthest from the sun. Perihelion is the correct answer.
The total number of moles of solute particles present in 1L (exact) of aqueous 0.057 m hno3 is 0.166 mol
Initial moles of HNO3 = 1Lx 0.083 mol HNO3/1 L
The HNO3 is a strong acid that can be completely dissociated in the following way.
HNO3→H + NO
1 mol 1 mol 1 mol
The HNO3 is dissociated into two particles (Kt and NO3). So that,
total moles particles = 0.083 mol (K) + 0.083 mol (NO) = 0.166 mol
The number of moles of solute = mass of solute ÷ molar mass of solute, where mass is measured in grams and molar mass (defined as the mass of one mole of a substance in grams) is measured in g/mol.
