120 ag. The mass of 1.0 × 10^6 molecules of dimethylnitrosamine is 120 ag.

Step 1. Convert molecules to moles

Moles of DMN = 1.0 × 10^6 molecules DMN× (1 mol DMN)/(6.022 × 10^23 molecules DMN) = 1.66 × 10^(-18) mol DMN

Step 2. Convert moles to grams

The formula for dimethylnitrosamine (DMN) is (CH3)2N-N=O or C2H6N2O. The molar mass is 74.08 g/mol.

Mass of DMT = 1.66 × 10^(-18) mol DMN × (74.08 g DMN/1 mol DMN)

= 1.2 × 10^(-16) g DMT = 120 × 10^(-18) g = 120 ag

i'm wiling to try and you : )

i think its 100.

hope this !
