The molar mass of glucose is 180.16g/mol. So to convert grams of glucose into moles of glucose, divided the mass in grams by the molar mass, and grams will cancel out leaving you with moles. 120g / 180.16 g/mol = 0.666 moles
It’s the third step of the scientific method
Since the equation for density is d=m/v, you can multiply both sides by m in order to get m by itself {d(v)=m}. Plug the volume and density in (1.1x7.9) and you will get 8.69. If you are using proper sig figs, then it will be 8.7g.
Hello! The reactions are catalyzed, or sped up by enzymes. Enzymes have strict conditions they can work under, including a small range of temperature. Temperature increase slows the rate of reaction, and extreme temperature increase can denature, or destroy an enzyme. Hope this helps! :)
