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

sure. show the steps you used to calculate it, and we can help see where or whether you went wrong.
R_Scott told you that your answre of 10% was good at 1:22 A.M. It should still be a good answer.
Here are my steps:
Mass % = mass of solute (g) / volume of solution (L) x 100%
= 1 /0.01 x 100%
= 10 000%
Mass % = mass of solute (g) / volume of solution (L) x 100%
= 1 /0.01 x 100%
= 10 000%
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%.
Oh no, the question that R_scott answered was a different one
