Molar mass CO2 = 12 + 16 x 2 => 44.0 g/mol
1 mol ----------- 44.0 g
2.1 mol --------- ( mass CO2)
mass CO2 = 2.1 x 44.0 / 1
mass CO2 = 92.4 / 1
= 92.4 g of CO2
hope this helps!
I understand here "bias" to be the uncertainty of measurements. So the order will be the following:
6.4 ± 0.5 s
<span>6.6 ± 0.1 s,
</span><span>6.63 ± 0.01 s,
</span><span>6.52 ± 0.05 s,
</span>
(notice how the second number, the one behind the symbol ± gets smaller, as the bias gets smaller).
