The mass of ice is the same as water because during a physical change, like a state change, mass is conserved. When the ice melts, all that changes is the physical state.
Volume = 20.0 cm³
density = 19.3 g/cm³
Therefore:
mass = density * volume
mass = 19.3 * 20.0
mass = 386 g
Hydrogen bonds or covalent but I’m sure it’s hydrogen
Answer:
True......................had to do this because we need atleast 20 letters
The number of particles of atoms depends on the ratio of their composition in the compound

Given
5.432 g of table sugar
Required
moles of sample
moles of C, H and O
number of atoms
Solution
Table sugar : Sucrose : C₁₂H₂₂O₁₁
= 5.432 : 342,3 g/mol
= 0.016
C = 12 x 0.016 = 0.192
H = 22 x 0.016 = 0.352
O = 11 x 0.016 = 0.176
C = 0.192 x 6.02 x 10²³ = 1.16 x 10²³
H = 0.352 x 6.02 x 10²³ = 2.12 x 10²³
O = 0.176 x 6.02 x 10²³ = 1.06 x 10²³
