Mary is an aspiring chemist, but not such a good programmer yet. She needs to implement the Avogadro constant in her code, but she doesn't know how to do it. She uses the approximation of NA = 6.022×1023 in her calculations.
Help her and complete the code with a double floating-point literal using scientific notation:
double nAvogadro = ... ; // type ONLY the missing literal to the answer
Type only the missing literal as an answer.
