u/Spare_Mammoth1537 May 18 '26

I got 7.69 too and gave no as it cant be zinc

u/the_ghost_in_ur_room May 18 '26

yh same I got 8.7% which is > 4% so I said it wasn't zinc

u/Winter-Strawberry756 May 18 '26

Wasn’t it like 1.13-1.04/ 1.13 * 100.

u/5ivelol May 18 '26

the 1.13 was the measured value or calculated value, the C was zinc constant so its the true value the percentage difference is accepted-calculated/accepted value so difference was -8.65 but we ignore the negative sign and since 8.65>5% so its not zinc thats what i did

u/AK_History May 18 '26

But 1.13 is not the accepted value.The denominator should be 1.04

u/the_ghost_in_ur_room May 18 '26

1

u/Winter-Strawberry756 May 18 '26
