Density

[The Detective]

Do we always assume a density of 1g = 1mL when it's not specified?

+

then could someone please explain this:

6.7μg in 1mL = 670μg in 100mL = 670μg in 10g?

Thanks

Yep, density is 1 if not specified

then could someone please explain this:

6.7μg in 1mL = 670μg in 100mL = 670μg in 10g?

Thanks

if 100mL = 10g, p = m/V = 10 / 100 = 0.1 g/mL. As p < 1.0g/mL, there is less mass mer mL.
