<span>In the written directions the indicator that the matter contains protein is when the solution turns a purple color. Therefore we can conclude that if your sample causes the solution of Copper Sulfate and Sodium Hydroxide to turn purple, it does indeed contain protein.</span>
First convert 0.163 grams of N2O to mol by dividing it with
the molecular weight. The molecular weight of N2O is 44 grams/mol. The answer
would be 3,79x10^-3. Then multiply it with 2 since there are 2 Nitrogen in one
mole of N2O. Therefore, there are 7.41x10^-3 moles of Nitrogen.
