Volume = V = 250ml = 0.25 L 
<span>M = 0.135M </span>
<span>Molar mass of AgNO3 = 108+14+3*16 = 170 </span>

<span>M = mole/V </span>
<span>mole = 0.135*0.25 = 0.03375 mole </span>

<span>mole = mass/molar mass </span>

<span>mass = 0.03375 * 170 = 5.7375 gr</span>

Answer:

Atoms_H=12Atoms

Explanation:

Hello,

In this case, the only source of hydrogen is in the 6 molecules of water, therefore, the atoms of hydrogen, by applying stoichiometry with the Avogadro's number is:

Atoms_H=6moleculesH_2O*\frac{1molH_2O}{6.022x10^{23}moleculesH_2O}\frac{2molH}{1molH_2O}*\frac{6.022x10^{23}AtomsH}{1molH} \\Atoms_H=12Atoms

Best regards.

Sholpan [36]

Answer:

the wax is a nonpolar substance that will not mix with polar water

Explanation:

Water is polar by due to the uneven distribution of charge between the hydrogen and oxygen. T=This automatically eliminates options 3 and 4.

Wax on the other hand is a non polar substance. Due to this non polar characteristic, it would not dissolve in water. The correct option is;

- the wax is a nonpolar substance that will not mix with polar water

How many moles are in 6 x 10^23 molecules of H2O
goldfiish [28.3K]
One mole represents 6.022∙1023 separate entities, just like one dozen represents 12 objects. So, if there are 6.022∙1023 H2O molecules, that is the same as one mole of water.
