Yes you can travel alone, but as you have US and Russian citizenship you should note this advice from the US Dept of State Bureau of Consular Affairs https://travel.state.gov/content/travel/en/international-travel/International-Travel-Country-Information-Pages/RussianFederation.html
βMinors who also have Russian citizenship and are traveling alone or in the company of adults who are not their parents, must carry a Russian passport as well as their parentsβ notarized consent for the trip, which can be obtained at a Russian embassy or consulate, or a U.S. notary public. A consent obtained in the United States from a U.S. notary public must be apostilled, translated into Russian, and properly affixed. Authorities will prevent such minors from entering or leaving Russia if they cannot present this consent.β
