Solution with a ph of 7 Is neutral
Total mass of mouthwash = volume*density
1 pint is 568.261 mL therefore 1.040 pints = 591.0 mL (4 significant figures)
Therefore mouthwash mass in a bottle = 591.0 mL * 0.851 g/mL = 503 g (3 s.f.)
In 160 bottles, ethanol mass = 509 g * 160 * 0.381 = 30700 g = 30.7 kg
Answer:
B.) an intensive property
Explanation:
Bc it is a Characteristic Property that won't change no matter what size of sample is tested
<span>When electrons are excited they get more energy and jump to higher orbitals. As they loose that energy that had excited them in the beginning, they tend to return to their original orbitals and the color that is given off is when this is occurring. </span>
