The cost of one antacid is 2.325 cents per tablet.
<u>Explanation:</u>
As per the question based on the student analysis we know that,
Total antacid tablets in a bottle = 120
Purchase Price of a bottle = $ 2.79
Cost of 1 antacid tablet
As we know $1 = 100 cent
The cost of 1 antacid tablet = × 100 cents = 2.325 cents/tablet
.
Thus we came to know that it costs 2.325 cents/tablet .
Answer:
e. 4.847 x 10-19 J
Explanation:
From the given information:
The equation connecting the photon energy and the wavelength is:
where;
= 6.626 * 10 ^{-34} J.s
= 3.00 * 10^8 m/s
wavelength
To determine the photon energy of violet light
= 4.847 × 10⁻¹⁹ J
Answer: the boiling point elevation constant is
Explanation:
Elevation in boiling point is given by:
= Elevation in boling point
i= vant hoff factor = 1 (for non electrolyte)
=boiling point constant = ?
m= molality
Weight of solvent (diethylether)= 330 g = 0.33 kg
Molar mass of solute (benzophenone)= 182 g/mol
Mass of solute (benzophenone) = 38.2 g
Thus the boiling point elevation constant is
