The nutrition label on a bottle of cola reports that a 8.0 fl oz serving contains 25 g of sugar. How many kilograms of sugar are
Sedbober [7]

Answer:

0.21 kg  

Step-by-step explanation:

      Volume of cola = 2.0 L × (33.8 fl oz/1L)

                                = 67.6 fl oz

     Grams of sugar = 67.6 fl oz × (25 g sugar/8.0 fl oz)

                                = 210 g sugar

Kilograms of sugar = 210 g × (1 kg/1000 g)

                               = 0.21 kg

Please help with Chem I DON'T HAVE ENOUGH TIME!
Kamila [148]

<u>We are given:</u>

Mass of water: 119 grams

We know that one mole of a gas occupies 22.4L of volume

<u>Number of moles of water:</u>

Number of moles = given mass / Molar mass

Number of moles = 119 / 18             [molar mass of water = 18 grams/mol]

Number of moles = 6.61 moles

<u>Volume occupied:</u>

Volume = number of moles * 22.4 L

Volume = 6.61 * 22.4

Volume = 148L

Volume (in mL) = 1.48 * 10⁻¹ mL
