To get moles. divide mass by molar mass.Molar mass of
Na is 23
and for Cl is 35.5.
the total molar mass of NaCl is 23+35.5 = 58.5mol/gUse the mass and divide by this number30.22g divide by 58.5mol/g and you will get 0.5166 mole.
Since the molecule has 1 Na to 1 Cl, and that the number of moles for NaCL is 0.5166. All of them would be 0.5166molesNa = 0.5166 x 1 = 0.5166molesCl = 0.5166 x 1 = 0.5166moles
to get number of atoms. Multiply your mole by Avogadro number which is 6.022x10^23Na = 0.5166 x 6.022E23 = 3.111x10^23Cl =  0.5166 x 6.022E23 = 3.111x10^23

Alchen [17]

Answer:2-methylpropane

Explanation:

The structure of 2-methylpropane is contrasted with that of propane in the image attached. It is easy to see that 2-methylpropane contains a tertiary carbon atom which forms a stable radical. This stable radical formed will eventually lead to the yield of a single product which is 2-chloro-2-methylpropane. A tertiary radical is the most stable radical and often leads to the formation of a single product.

Molodets [167]

Answer:

Why science communication is important? In the world we live in, not only does pursuing science matter but communicating about it effectively is important as well. Communicating about science is crucial, whether we communicate about it online or face to face, communication about the scientific facts is vital for the scientific community. This is especially important now when many question scientific methods, research, and results. We are not only talking about communication about science between academics, scientists and corporations, but we are also talking about the gap between the scientific world and non-scientific community.

A column is packed with 0.5 g of a strongly acidic ion exchange resin in H+ form. A 1.0 M NaCl solution is passed through the co
Lena [83]

Answer:

The correct answer is 17 meq/g

Explanation:

Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.

The exchange Reaction can be represented as

R-HR-H^{+} +  Na^{+} + Cl^{-} -> R-Na^{+} + HCl_{aq}

The IEC value (in meq/g) is determinated by using the next equation:

IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin

IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g
