Answer:
yes your answer is correct
True
Explanation:
Metallic bonds joins atoms of metals and alloys together. The formation of this bond type is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.
- This bond type is actually an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all atoms.
- Some of the physical properties of metals such as malleability, ductility, electrical and thermal conductivity, luster, high melting point e.t.c stems from this.

Take 234/100 x 0.01
then 235/100 x 0.71
then 238/100 x 99.28
you divide by 100 because the abundance is given in percentage over 100
then add up all the values, you should get an answer of 237.97 rounded up is 238.
Final answer : 238
hope this helped :)
Answer:
Explanation:
To convert from representative particles to moles, Avogadro's Number: 6.02*10²³, which tells us the number of particles (atoms, molecules, etc.) in 1 mole of a substance.
We can use it in a ratio.
Multiply by the given number of molecules.
Flip the ratio so the molecules of water cancel out.
Divide.
The original number of molecules has 2 significant figures: 3 and 1, so our answer must have the same. For the number we calculated, that is the tenth place. The 4 in the hundredth place tells us to leave the 1.
There are about 5.1 moles of water in 3.1*10²⁴ molecules of water.
