12.0g x 1 mol / 63.546g = 0.188839581mol
<span>So, for every 1 mole, we have 6.022 x 10^23 of whatever we're measuring. This gives us a conversion factor of (1 mole / 6.022 x 10^23 atoms) or (6.022 x 10^23 atoms / 1 mole).
</span>
0.188839581 mol x (6.022 x 10^23 atoms) / 1 mol = 1.137191955 x 10^23
<span>Remember from before that we are limited to 3 significant figures. Since our calculations are complete, we can now round down to: 1.14 x 10^23 </span>
<span>That should be your answer!
Hope it helps!

Anything that occupies space and has mass.
Because sucrase will react with product and lower his concentration, so measurement of product concentration will not be accurate.
Sucrase activity is greater when sucrose concentration went from 2.5 to 7.5 g/l, because difference (increase<span>) between two concentration (numbers) is greater.</span>
1: parent alkane.
2: polymers
3: idk
4: alkynes
5: its either n-butane or isobutane
6: saturated hydrocarbons
7: i'm not sure but I think it's Lewis Dot Structure and Polarity. ... Benzene
8: Idk
9: I'm not sure either
Hope this helps! :)
Water's specific heat capacity is 4200 J/Kg°C
95-28=67
72.5grams in kg is 0.0725kg
Energy = 67×0.0725×4200
Energy = 20,401.5 J or 20.4015 kJ
