Answer:
See explanation
Explanation:
The mole refers to the amount of substance contained in 12 g of carbon-12. It was arbitrarily related to the number of elementary entities in 12 g of carbon -12 by Prof. Avogadro.
The number of moles of a substance is obtained as the mass of the substance divided by the mass of one mole of the substance (molar mass). Hence when the number of moles is known, the mass is now;
number of moles * molar mass
To determine the cost of one sip of wine, we first calculate the cost of wine per unit volume. For this case, we need to convert the volume to milliliter for simplicity. We calculate the cost per volume as follows:
cost per volume = $ 278 / 24.5 fl oz ( 1 fl oz / 29.57 mL )
cost per volume = $0.38 / mL
To determine the cost of one sip, we multiply the volume of one sip to the cost per volume.
cost of one sip = $0.38/mL ( 2.0 mL ) = $0.77
