Question

If a solution is made by dissolving 1 g NaCl in sufficient water to make 10 mL of solution, the composition of the solution is what % w/v?

I keep getting 10 000% but that doesn't seem right at all. Can someone check this for me. Thanks to anyone who helps

Answer 1

sure. show the steps you used to calculate it, and we can help see where or whether you went wrong.

Answer 2

R_Scott told you that your answre of 10% was good at 1:22 A.M. It should still be a good answer.

Answer 3

Here are my steps:
Mass % = mass of solute (g) / volume of solution (L) x 100%
= 1 /0.01 x 100%
= 10 000%

Answer 4

It appears to me that 10 000 does not mean 10.000%. I would use a period to avoid confusion. In the U. S. I would write that as 10.000%.

Answer 5

Oh no, the question that R_scott answered was a different one
