- freezing point for a solution of 35 g/L NaCl: -2 deg. Celsius- density for a solution of 35 g/L NaCl: 1,025 g/cm3- thermal conductivity for a solution of 35 g/L NaCl: 0,6 W/m.K
if 200 mL of 0.2 M of zinc hydroxide is diluted to a point where its volume increase by 35% what is the OH concentration?I got 0.29 M which is probably not right

Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
It is 11.3
Molarity means the number of mol of a substance per 1 litre of substance. Or figure out the number of mol of NaCl ((2.60/(23+35)=0.04) then multiply the 35ml by 28.571428 to get that to litres.. then multiply the number of mol by 28.571428 to get that to the number of mol. Therefore the answer is 1.142857M. See the Related Questions link "How do you prepare a solution of a specific concentration?"

A: 10.172 M HCl. Percents of acids like this one is normally given in % w/w, or percent weight by weight. So we need to find the mass of the solution. Molarity is moles of solute per liter solution, so we will calculate this for 1L of solution. The density of 32% HCl is 1.159 g/mL. So assuming we have one liter or 1000 mL, the weight of the solution is 1159 g. If 32% of this is HCl, we have 1159 g solution * 0.32 g HCl/g solution = 370.88 g HCl. The molar mass of HCl is 36.461 g/mol, so 370.88 g HCl * 1 mol HCl/36.461 g HCl = 10.172 mol HCl in 1 L of solution. 10.172 mol HCl/1L solution = 10.172 M HCl.
35% of 60= 35% * 60= 0.35 * 60= 21
The answer is 35%. Solution: 70/200x100 =0.35x100 =35%
If 6x-7=35 then 6x=35+7=42 and x=7
The equation is [ 5y = 35 ].The solution to the equation is [ y = 7 ].

during acid base titration a base reacts with acid molecules not with water so when 35 ml solution is diluted with water the no of molecules of acid remains the same.... so reading does not changed...
