Answer;

They are compounds

Explanation;

A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds.

When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.

Elements are substances that cannot be separated into simpler substances.

Calculate the number of sucrose molecules in a 75.0 gram sample.
zzz [600]

Answer:

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)
