How many grams of sodium chloride are required to make a 1.0 L solution with a concentration of 3.5 M?

2 answers:

8 0

The molecular weight of NaCl is 58.44; sodium =22.99; Chlorine=35.45.

<span>A 1 molar solution is the molecular weight in grams in 1 litre of water,
So, a 3.5 molar solution would be = 58.44g * 3.5, 204.54

In short, Your Answer would be 204.54

Hope this helps!</span>

3.5 M has 3.5 moles per litre
so we have one litre, so we need 3.5 moles
moles = mass/molarmass
3.5 * 23 = 80.5

Question 14 of 17

artcher [175]

Since Lutetium-177 is a beta and gamma emitter, the daughter nuclide produced from the decay of this radioisotope is 177Hf.

Beta emission of a radioisotope yields a daughter nuclide whose amass number is the same as that of its parent nucleus but its atomic number is greater is greater than that of the parent nucleus by 1 unit.

Also, gamma emission does not lead to any change in the mass number of atomic number of the daughter nucleus produced.

Hence, the stable daughter nuclide, 177Hf is produced.
