help meeeee

[destain]

An ore sample (nickel content to be determined) was prepared for analysis by
digestion of 1.35g of ore in acid and made up to 10ml.
This solution was then diluted with distilled water to 100ml.

Conc. of nickel ions in mg/L in the diluted sample is 1.24 x 10^-3 mg/L

1) Determine the mass of nickel, in mg, in the ore sample.

-Either im fried or the answers are wrong OR i missed something

1.24E-4 mg?

You sure its 1.24E-3 mg/L or 1.24E-3 g/L?

WOWOWOWOWOW THATS WHERE IM WRONG, ITS 10^3 NOT -3
WTF WOW IM PUTTINGA  NEGATIVE IN FRONT OF EVERYTHING o

NO WONDER THE CALIBRATION GRAPH I DREW WAS SO WEIRD WTFFFFFFFFFF

thank you
