Answer:
The number of molecules is 1.4140*10^24 molecules
Explanation:
To know the number of molecules, we need to determine how many moles of water we have, water has molar mass of 18.015g/mol
This means that one mole of water molecules has a mass of 18.015g.
42.3g * 1 mole H2O/18.015g
= 2.3480 moles H2O
We are using avogadros number to find the number of molecules of water
2.3480 H2O * 6.022*10^ 23moles/ 1mole of H2O
That's 2.3480 multiplied by 6.022*10^23 divided by 1 mole of H2O
Number of molecules = 1.4140 *10^24 molecules
It deteriorates. Definitely more than when you started.
Gravitational force will increase with greater mass
Answer:
the action or process of filtering something.
Answer: 4.5165 *10^-23 moles Carbon
Explanation:
There are 6.022*10^23 atoms in a mole.
Therefore, there would be 6.022*10^-23*0.75 atoms in 0.75 moles of Carbon.
= 4.5165 *10^-23 moles Carbon
