Sodium Chloride (NaCl) has a molecular mass of 58 grams/mole. What is the molarity of a NaCl solution with a

Vera_Pavlovna [14]

Answer:

2nd option

Explanation:

Molarity is the number of moles of the solute (NaCl) in 1 litre of the solution (NaCl solution).

Given: concentration= 232g/ L

what we are trying to achieve is __mol/ L.

So in 1 litre, we have 232g of NaCl.

To convert mass to mole, we divide it by the Mr.

Given that the Mr is 58g/mol,

number of moles

= 232 ÷58

= 4

Thus, 1 litre has 4 moles of NaCl.

Therefore, the molarity is 4.0 mol/L.

A certain person had a brain that weighed 1.45 kg and contained 6.41 × 1010 cells. assuming that each cell was completely filled

PilotLPTM [1.2K]

Weight of 6.41×1010 number of cells is 1.45 Kg i.e, 1.45× $10^{3}$ gm. So, Weight of 1 (one) number of cells is= $\frac{1.45X10^{3} }{6.41X1010}$ gm = 0.2239 gm.

Assuming that each cell was completely filled with water, from density, Volume of 1 gm water is 1 ml, so volume of 0.2239 gm water is 0.2239 ml. That means, volume of each cell is 0.2239 ml= 0.2239× $10^{-6}$ m³. If each cell is considered as cube, volume of cube=(length of each side of cube)³= 0.2239× $10^{-6}$ m³.

So, length of each side of cube= ∛(0.2239× $10^{-6}$ = 6.07× $10^{-3}$ meter.
