Question 415140
Add the two samples together to give you 100%

6.942 + 0.178 = 7.12 = 100%

Divide 100% by the total sample to give percent for 1 gram.

100/7.12 =  14.044943% for 1 gram

Multiply by the pure seed value

14.044943 * 6.942

= 97.5%

You can verify by multiplying the 14.044943 by the weed seed.

14.04493 * 0.178

= 2.5%

97.5% + 2.5% = 100%
