Answer:
Number of moles = 2.89 mol
Explanation:
Given data:
Number of moles of sugar = ?
Mass of sugar = 990 g
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of C₁₂H₂₂O₁₁:
12× 12 + 22×1.008 + 16×11 = 342.2 g/mol
Number of moles = 990 g / 342.2 g/mol
Number of moles = 2.89 mol
Answer:
5
Explanation:
An atom has the same number of protons and electrons
Cation and an anion the differences in charge make them attracted to each other
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in another
