1.31*.3=.393 mols NaCl.
This also equals .393(22.99+35.45)=22.97 g NaCl.
To find the amount of NaCl in 1.84 L of 0.200 M NaCl, you use the formula: amount = concentration x volume. Thus, amount = 0.200 mol/L x 1.84 L = 0.368 mol of NaCl.
8.44 mci l-131 = -122.56
The sea water contain approx. 35 g/L NaCl.
Divide grams (mass) by molar mass to find moles58.44 (g NaCl/L) / [22.99+35.45](g NaCl/mol NaCl)= 1.000 mol/L NaCl
You need 58,44 mg of ultrapure NaCl; dissolve in demineralized water, at 20 0C, in a thermostat, using a class A volumetric flask of 1 L.
- 0,9 g/L NaCl equal to 0,154 moles - but because NaCl is dissociated in two ions in water the relation is 1 mol NaCl equal 2 osmol/L - and so 0,9 % NaCl equal 308 milliosmole/L
The concentration of the NaCl solution is 29.25 g/L. This is calculated by dividing the mass of NaCl (58.5 g) by the volume of the solution (2 L).
2M NaCl is a equivalent to a solution with 116,88 g NaCl in 1 L water.
9 g/L NaCl = 0,9 g/100 mL = 0,154 moles/L = 300 mOsm/L
This is equivalent to a concentration of 6,73 g/L NaCl.
The concentration of NaCl is 263 g/L
The concentration of NaCl in sea water is about 35 g per kg. The density of seawater is about 1.025 kg/l, so you would need 50 * 1.025 kg sea water for 50 liters of solution.NaCl contributes to this with 35 * 1.025 * 50 g / kg * kg / l * l. consequently the result is about 1794 g of NaCl.
