Answer:
one mole of water contains 6.02 x 1023 MOLECULES of water.
But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

Answer:
The volume of carbon (ii) oxide present is <u><em>2.80 L</em></u>
Explanation:
In this question, we are asked to calculate the volume of a certain number of moles of carbon (ii) oxide sealed in a container at STP
The equation to use here is the ideal gas equation.
Mathematically;
PV = nRT
since we are to calculate the volume, the equation can be re-written as
V = nRT/P
The values according to the question are as follows;
n is the number of moles which is 0.125 moles
T is the temperature at STP which is 0°C = 273.15 K(kelvin)
P is the pressure at STP which is 1.0 atm (atmosphere)
R is the molar gas constant which is 0.0821 L.atm.
Plugging these values, we have
V = (0.125 × 0.0821 × 273.15)/1 = 2.80 L
The elements are electrically neutral, this is they have the same amount of positive as negative charge.
Electrons and protons have each the same amount of charge but different sign. Eletrons are negative and protons are positive.
Then to be neutral, the number of electrons must be equal to the number of protons. This mean that the element must have 12 electrons.
