The perfect glass of sweet tea is 15% sugar. Elena is making a one gallon container of sweet tea. How many cups of sugar are in
Arte-miy333 [17]

There are 2.4 cups of sugar in the gallon of sweet tea.

<h3>What is the conversion of fluid measurement?</h3>

The conversion of fluid measure takes a standard analysis where the assumed container of a particular fluid is related to another container.

For example, we have two containers here:

  • The glass cup
  • The gallon

We need to know how many glass cups that are present in a gallon. From standard conversion rates:

  • 1 gallon = 16 cups

However,

We learned that 1 cup contains 15% of sugar; Therefore, 16 cups will contain:

= 16 × 0.15

= 2.4 cups of sugar

Explanation:

2H2O2 => 2H2O + O2

Moles of hydrogen peroxide = 0.150dm³ * (0.02mol/dm³) = 0.003mol .

Moles of oxygen = 0.0015mol.

Volume of oxygen = 0.0015mol * (22.4dm³/mol) = 0.0336dm³.
